Ok, I looked at both your charts and I can honestly say without any judgement based on your comments that he is truly the problem in your relationship. In terms of compatibility, you have a couple planets I believe it was Venus and one other that connects to his Sun, Mer, Mars, and Venus, but not a whole lot more. I will look again, but want to comment on him first. I can clearly see that in general, even though you have a Capricorn rising ASC, you are someone who in general is not prone to be overly emotional by nature with a Sag Moon. It seems that your parents were divorced which is indicated by Sun Square Moon or at the very least, they were disconnected with each other and might have stayed together for the kids sake. I am curious about Mars there in your 4th house. My first thought was that there was abuse from one of your parents or maybe they were very strict with you, possibly militant in nature. I believe this colors your relationships, although it's not badly aspects(Mars that is) so maybe it was ok. I am going to be honest with you, I am not crazy about this guy at all. He is a bully and probably has the ability to be very argumentative and cruel if he wants to, and I don't have any doubt that he has. He has Sun, Mercury, Venus, and Mars all square to Uranus and Pluto. I bet he has the ability to cut someone down to the core with his words. Martial Arts would or a very grueling contact sport like Rugby would be a great way to work with these energies in a positive way. He is also prone to depression with Moon conjunct Saturn. Remember what I said about "liking the chase?" He is absolutely someone that likes what they can't have. Trust me on this one. Not only does he have Uranus on the cusp of the 7th house of love and love and romance, it's in challenging aspect to all his personal planets. Since Pluto is involved, there are likely power struggle in his relationships to. In terms of liking what he can't have it can come in many forms, someone is married, living away, or simply not interested in him. This is what peeks his interest subconsciously and when he lands in a relationship, he will sabotage it because deep inside of his subconscious he will feel dissatisfaction and the grass is greener elsewhere.
As for what is happening now, you have a lot of challenging things going on...Transiting Saturn opposite Uranus, Transiting Uranus square Saturn, transiting Pluto opposing Pluto. These are generational transits, so you will have to look to the rulers of the house they are affecting as well as the planets and what house they are placed in. In a short while this year, you will have the first transit of Saturn squaring your 7th house angle or cusp. At the same time, it will oppose your boyfriends Moon Saturn conjunction. This could be a time where you break up or have more problems although the first transit(it happens two more times for a total of 3 times)is not as strong. The second time which i believe happens in the Spring will likely be much stronger with the final transit I believe late summer the last and sometimes strongest. I suspect your boyfriend will be more upset that you will be oddly enough since it affects his Moon and he has a Moon Saturn conjunction natally, which makes it more strongly felt when you have the same to planets aspect natally as well as transit wise.
I think you could find someone that you could have better synastry with, but I understand the physical attraction for sure.
My applogy, I just noticed I misread the degree of your ASC/DEC. Please disregard what I said about Transiting Saturn hitting your 7th house cusp, this has already passed quite a while ago. So with that said, i don't beleive you will break up quite yet, although what I said about his depression later this year still holds true. When Transiting Pluto moves over your ASC (the fist hit in about a years) you will go through quite a transformation personally.
