Boyfriend problems...

So me and my boyfriend been together around 3 months and when we first started dating we was perfect. We barley really argued and now it’s like we can’t go 3 days without arguing. Even if it’s over small stuff. And it’s like we never go on dates or anything. He doesn’t want me hanging with him and his friends anymore. Idk it’s like he’s changed so much. He doesn’t want to be around me as much anymore. Idk what to do to fix it. I literally do everything for this guy. I pay his way right now since he hasn’t had a job in awhile and i just don’t know what to do to fix our relationship.
