Not sure how I should feel about this

Mya

If it's not one thing its the next, my bf & I got into an argument about the same thing that just started the ending of last year. This time around I just brush the situation off cos there's no point or worth my energy to even talk about it but I'm just getting more and more fed up inside. Our communication is already bad, I've tried to talk to him as calm as possible but he just always ends up turning it into an argument. So its like I keep things to myself he thinks everything is fine, we're good. But when I bring up what I feel is going wrong, I'm the one who is wrong. But outside looking in, everyone agrees with me. But that's not the point, earlier today as we got into an argument, he called me by his ex name. Should I just brush it off, leave him? I can't even look at him, cos thoughts of how fucked up he has been just pops back into my head.

Its been four years since their breakup. She left him, and they were H.S sweethearts, his first GF. I know he still loves her, and misses her. Mentions/Reminisce about her every now and then. And I know he still has hope for them to workout, crazy as it sound.

I don't know.
