Can I fix him?

N.O, and its unfair that you even want to try. You did say you like guys who are mean to you, so I don't actually see the problem here, unless you've changed your mind about preferring to be ill treated...

We choose our partners because we love and like them as is. Not because we see potential for what could be and try and mould them accordingly.

That being said, if there are certain issues in our relationships that need addressing, yes we communicate our needs and work together on a compromise. But the objective should never be to fix or change someone into our ideal partner.

Instead go and search for him / her.

Is it you? Idk, I'd have a problem with being called names, being disrespected and being blamed for everything that goes wrong. Means my bf firstly does NOT respect me, and also either refuses to accept accountability / responsibility or lives in Lalaland. Either way I cannot build a future with such a person or even tolerate such behavior because he and I will be on 2 very different chapters nevermind pages.

Communication is key. If he's not willing to respect you, and meet you half way, well then you know what to do.
