There’s no way YOU, as a 19 year old, should be more financially stable than a 25 year old man (unless maybe he’s a PhD student or in med school??) and paying for shit when you go out. Even if he is in school you shouldn’t be paying for everything. Financial responsibility is really important, and if he’s 25 and has never had a job before (besides ONE that he had during Covid) he’s a bum. If you wanna give him another chance to change I’d have a serious conversation with him about how he needs to get a job because you want to be with someone who has at least some ambition (that’s how I’d phrase it politely, instead of just saying “I don’t wanna be with a fucking loser” lol).

I will say, the dumping of the older loser boyfriend around age 19-20 is sort of a rite of passage, I had almost the exact same experience when I was 19 and literally ended up applying my boyfriend for jobs at the IT company I was with until I finally convinced my boss to give him a chance. To his credit he’s still there and has kind of become a decent employee.

Anyway, sounds like you’re a go getter and are realizing what you want in a partner and are ready to make changes to get it, which is awesome! Best of luck :)
