Boyfriend advice!

My boyfriend and I have dated before but we broke up.We got back together about 3 months ago.Since quarantine started he barely ever talks to me and always says he's busy.I mean he can't possibly be busy every single day,can he?He also doesn't really know a lot about me and doesn't even make an effort to get to know me.He tells me he loves me and stuff but how can you love someone you don't even know?He makes me so mad but at the same time I can't even think about leaving him.I don't really want to talk to him about it because whenever I do he changes the subject and I don't want to start a fight.Should I leave him or wait?Maybe he changes.(we're both 14 btw)
