>>1 I think that you should talk with him about it. If he had sexual/intimate things with you then he mostly likely might be bi. Tell him that you want a legitimate relationship sometime in the future, I'm guessing you're still in highschool? If you're still in highschool then I'd wait on the official relationship, but you still need to talk to him about cheating on his girlfriend. It makes you feel bad and that's not fair, it might be hurting her too. Talk to him about it okay? If he really cares for you then he'll understand, there is a chance that he's using you too so be sure to talk to him about the two of you seriously, it might be hard but it is necessary to do so sometimes. Good luck, I hope I helped ^^
