Hey there.
So let's look at each of you individually first.
The very first thing that I notice is that your husband is under the influence of transiting Pluto squaring his natal Saturn (in its fall in Aries). This right here shows that he is dealing with some intensely personal issues. Pluto and Saturn are both planets known for bringing pain, limitation and depression. Of course, this is not just for the sake of making a person miserable, it's usually so that they can get 'unstuck' because they are forced to fight their way out of a tough spot.
Pluto (in Capricorn) squaring Saturn here to me says that your husband is feeling at odds with everything around him. All of the structures that he has had in his life are at this time feeling like they are bringing him a great deal of confinement. Most certainly, he is examining everything extremely critically and Pluto will make sure that he sees things for what they are with no frills or rose colored lenses.
What's more, is Transiting Uranus is coming into an applying conjunction with Natal Saturn and an opposition to both of your natal Uranus'. This is enough of a combo to make anyone begin to feel more than a little batty as this is the quintessential mid life crisis aspect.
The best thing that you can do in regards to this transit is give yourselves LOTS of space and don't judge any changes that either of you are making in your lives if you want to stay together. They will be permanent changes so this is a good time to really reflect on what YOU want. There is a chance that you are growing in opposite directions, but you can minimize the impact of this by staying calm, centered and focused on your own development. I try to stress that aspects from the outer planets are not times to hang on tight, but rather to let go and see where the tempest drops you. You literally have to work with wherever the chips may lie.
Mars has been making a long trek through Virgo in both of your 2nd houses which mirrors the idea of fundamental change for both of you. We see that Pluto and Uranus are in Virgo for both of you as well. Mars has quite an explosive relationship with both of these planets, so having him march back and forth over them in the natal chart can make anything sticky, messy and ugly. In your 2nd house, we see that Mars is stirring up emotions and such by making you both very focused on yourselves and your possessions as well as your fundamental ideas of right and wrong. However, everything you have and know seems to be hanging on by a tenuous thread. The real purpose of any loss here is to get you to focus on the 2nd house matter that seems to get lost these days. VALUES. What do you value? Why? Is it still helping you? Are you trying to hang on to things that you should have maybe dropped a while ago?
Finally, you have transiting Saturn moving on and off of your sun repeatedly. This for your personally, can be a time of insecurity. Saturn is right on your sun and causing you to second guess even more things. Saturn in Libra calls into question issues of fairness and balance, especially in relationships. Are you being fair? Is he? What is fair?
So, just looking briefly at the natal charts alone. It's quite obvious that both of you are going through some very real changes.
Looking at the synastry, I don't see a lot of personal contacts that allow relationships to survive times like these. The biggest contacts you have to each others charts are from the outer planets showing that this has been a strongly karmic relationship and perhaps it is now time to let go as you have fulfilled whatever purpose that you shared.
