HIM WHY?!!! HELPPP

Okay so my bf broke up with me because apparently he wants to focus on his school work and L. But he started flirting with other girls and calling them pretty and shit anyways he says he doesn't want to completely lose me and wants to get back in the summer or some shit this was like 2 weeks ago. He still like snaps me and gives me attentionand we still hangout just as friends but this is what happened today also he's got bipolar disorder aswell but idk how bad his is. So this is what happened later on we were hanging out earlier & there's a party on friday also there's a grouo chat on snap for the people who are going but he was like "who u gonna fuck at the party" and i said "no one", and he was saying that id make out with a whole bunch of guys but i told him i wouldnt cause literally i only want him& that i wiuldnt makeout with a whole bunch of guys even if i was piss drunk but ive been trying to move on from him. but this was the our convo after he left today and he its his habit of blocking ppl then adding the back for some reason. BUT WHY IS HE ACTING LIKE THIS, WHY is being like this can someone explain or what u guys think he's trying to do, like does he still care for me
