Am I being selfish for staying with my girlfriend if I can’t provide her with my best self because of issues?

I’m going through a lot of fucked up shit. I’m being a father of my mother and 3 siblings. Abusive dad got jailed I called the police. And I can’t feel any emotion and my mums childish had me at 19 so never fully grew up.

I have a beautiful girlfriend and she’s really nice am I selfish for staying with her and perhaps holding her back?

I want to give everything in the future but maybe she’d rather have someone normal you know?

Like she can go to their house meet their family and shit rather than my ass who has basically nothing and a fucked life.

What do you think guys?

If you could look at my other previous posts too it’d show a bit of my story ig and the situation I’m in right now
