Agam -
I am looking concurrently at your natal/transits chart.
You have a natal moon-venus trine in 7th / 11th houses - which indicates a great deal of emotional desire for relationship - you are a person who aspires to being in a relationship. That is the first indicator for me that says future relationship(s) will be at the forefront of your concerns. In itself, it is not bad, but the risk, of course, is that your desire and need to be in bonded coupling can or might lead you into quick couplings which may or may not work out if the immediacy of need and desire eclipses the practicality. I believe you will have other relationship(s) given this moon-venus need, but I would caution you to spend time expelling the current grief and dismay you are feeling so that it doesn't cloud your thinking or acting. In other words, watch out for the 'rebound' relationships.
As I suspected earlier in my first post, without seeing your chart - you do have a Neptune influence with it being square to your venus. This can often imply a rose-colored-glasses approach to a relationship - seeing what you hope to see in other, but not necessarily reality based, and it has potential for clouding your perceptions of the other. This might have been operative in your relationship with your wife - you may have missed some of the signals/behaviors that might have indicated she was unhappy in the relationship and/or wanting to be with someone else. Be mindful of that stuff in the future. With Venus-Neptune it is always important to remember that feelings of love are often different than facts of love.
You have a very tight moon-mercury opposition from 11th to 5th - and this tells me that you are young at heart, and generally, there is an optimism of native with any moon-mercury aspect. But you also have a Moon-Saturn sextile, which lends excellent practicality and tempering of emotional overboard-ness, so count your lucky stars for that one. Although this hurts now, you will overcome it.
I want to add that Neptune, ruler of your Asc. in your 10th, could make you for a mark, as the saying goes. It means that you might be an easy target for being fooled, deceived or caught unaware. Again - this is what you have to be concerned with in the mates you attract, especially considering your venus-neptune aspect. It is possible that you could be targeted by less than honest people in matters of the heart and it can definitely create problems with your standing in the world around you.
Uranus sure did show it's upsetting ways in this instance with your wife. What you thought you had regarding 10th house status (your position has husband, head of household, etc) will always be a point of uncertainty, with quick or sudden lightning strikes of change in this area for you. I'm not sure when all of this transpired with your wife, but chances are that transiting Uranus, now at 21 of Aries, had perfected a trine to your natal Uranus in 10th around the time she told you she wanted out of the relationship. A trine of Uranus to Uranus by transit might sound good by aspect, but it is always going to be a point of upset and disturbance no matter what aspect is involved. The good of it is that it "freed" you from something that wasn't genuine. Find comfort in that if you are able.
As for future marriage/commitment, the ruler of your 7th, Mercury, is located in your 5th house natally. This, to me, tells me that maybe part of your 'freeing' by the Uranus transit was to show you that maybe you aren't necessarily needing the commitment of legal marriage as much as you are the the coupling / being with another person. With this, it likely provides you with ample opportunities for romance in life, and likely, with women younger than yourself.
I would caution you that transiting Saturn, although retrograde now, is soon to be applying to conjunct your natal Uranus in 10th - this tells me that your status as married couple, husband IS over, and that the parting of ways may be drawn out for a while, at least through to year-end. This doesn't have to be bad or prolonging, because it will allow you time to further process the reality of it all and by the time you are completely disengaged from the marriage (divorced) you will have had some time under your belt to review and put in perspective all that has occurred. It could also indicate that she might delay or push-pull the legality matter, since Saturn transiting 9th indicates matters of judgements in court that can be drawn out or taxing on one's matters.
All in all, I would say this: wait for Saturn to do it's number in 9th, then on natal Uranus, then 10th and then Neptune. (Sheesh, that sounds like a lot, butagain, thank your lucky stars that Saturn moves through a sign in two and a half years, so apply patience and tranquility where you are able.
Transiting Jupiter, retrograde now, will meet your 7th cusp cleanly and with finality in a short period, and Jupiter brings buoyancy to 7th - gives you a sense that others out there are on your side and with you for the haul. As well, it is kind of like a light at the end of the tunnel, and it may help pad the blow of all this once it crosses your Desc.
Your natal Hades Moon (moon-pluto aspect) is a whole 'nother story! Yikes, if you feel like getting vengeance or making overt attempts to control the situation or your wife at this point - please reconsider any actions, motives or behaviors of control or domination. 8th house Pluto seldom takes prisoners, so I am pretty sure you are boiling underneath the surface from all of this - and if there are issues of shared money/wealth/property, etc, involved, USE YOUR ATTORNEY to deal with these matters and don't take it upon yourself to crush your wife, because i get a feeling that is what this will come down to. 9 times out of 10 - when love is lost/removed, it becomes all about STUFF for a Hades Moon, as a means to capture who was lost by controlling things.
It will be a few years before Jupiter crosses your MC - sounds like a dreadfully long time, but assuredly, it's not that long in the big scheme of your life. Use that time to grieve, heal, repair and review and in the meantime, Jupiter will bring you ample opportunities for social and friendly relations with others who will help alleviate your current angst.
Once Jupiter gets to your MC, if you are still desirous of marriage and union, that will likely be the time - and after crossing Uranus, Jupiter will bring that optimism and good faith to you once again. You will likely also find true forgiveness for your wife at the point it conjoins your natal Neptune, and you will discover that if you really did LOVE her, you will be able at that time to let her go with no bad feelings.
But please - in the process - watch out for your Venus-Neptune inclinations to put others on pedastal - or just believing in love for the sake of being in love. Let your Moon-Saturn do the talking and thinking.
Your journey begins....
