My (23F) boyfriend (25M) finally broke up with me but said “nothing has to change”. He wants to talk tonight but I am out of arguments

My relationship has been rocky since I am struggling with mental health and trust issues. I constantly fear he will leave me for someone else which he did before, we got back together afterwards and I can’t fully let go of it.

I tried to make it work, but he finally broke up with me last night.

We have mutual friends who broke up and still stayed friends, still have sex etc.

I told him that I wouldn’t be able to cope with seeing him dating someone else who is “better” than me and replacing me etc.

He told me that he wanted to live his life, and that him dating someone else shouldn’t affect our relationship because relationships doesn’t have to be ‘boyfriend girlfriend’. He said when he left me for someone else during long distance wasn’t cheating, but that he was just living his life.

I kinda felt like this was going to happen as he will go on an exchange overseas in April for a few months and he doesn’t want a relationship where it’s restraining him.

I tried to argue that I cannot handle that thought. He wants to talk tonight about how our friendship going forward, and I don’t know what to say. We are in the same friend group. I feel like I would be excluded in my friend group now, but I know they should not be affected by us breaking up.

I’m terrible at arguments and would shut down. He always makes it as if he’s in the right. I need some advice on things to prepare to say to him.

We will still be living together for a while as I do not have any family or friends in the city, and my visa to stay in this country is dependent on him.
