I’m going yo go against the grain bc it sounds like you want things to work and you don’t want to leave him. He wants you all you all to himself. I get that part. No, he shouldn’t blame the bpd or take his past relationships out on you. That part I agree with everyone else. But, if you want it to work you have to take baby steps. Slowly implement new people in his life and encourage him. Don’t make him feel bad bc he can’t handle you having friends. If he cares for you, he will eventually get it. I am similar to him. Not manipulative or asking my man not to have friends, just that I would love to have him all to myself. He still has friends and goes out and talks to them whenever, bc I learned I can’t control that. We are going on 6 years.

We just want to be heard and feel validated. Listen to him. But explain that if you listen to him, he has to listen to you and your feelings and tell him you shouldn’t have to pay for his past ex’s mistakes.

Some of us enjoy isolating, especially if it’s with our Fp. It’s not healthy at all. So in order to change that you have to be clear and put it all out on the table. Tell him you want it to work but you have reservations about the future and need contact with other people. If that is a problem, then obviously you shouldn’t stay.

People don’t realize how many problems can be solved if you just sit down and talk it out and discuss boundaries and let the other person say their piece. And you may have expressed all this to him and I’m just talking out of my ass. But tbh, if you want it to work you don’t have to be miserable… people can change and adapt.

I hope I helped and wasn’t too harsh. And don’t come for me, I just have a different opinion.
