Thank you RxQueen for the response. To answer your questions:

I do have a therapist that we have been seeing together about our communication problems; he is lukewarm about it, so it's helped a little, but I know what it comes down to is that I can only change myself so I think it might be useful to make some individual appointments too.

I struggle with depression, anxiety, and the big underlying PTSD. I have a lot of sensitivities and anger issues revolving around my past traumas that have been revived recently and I am trying to work through them, and he wants me to forget about it and move on and acts offended if I don't.

He gets jealous of the remaining friends I have, and at times his insecurity and trust issues get the best of him, but I really appreciate that he is trying his best to accept the one remaining good friend I have. I feel like I am walking on eggshells though and have even pushed that friend away quite a bit.

I can relate to the blame game that you talk about with your bf, it is very frustrating because it is important to talk about your needs and feelings so that you can come to a solution as a couple but how is that possible if your partner attacks rather than listens? I think you are right about sticking to therapy and I hope I can try to find a balance with friendships and reassuring my SO about his insecurities.
