give up or try for the boy

So this guy and i started hanging out and immediately there was tension and eventually we kissed and then we hung out basically four days a week and never got sick of it and face timed till 2AM every night and had a lot fun. We werent dating, nor were we a "thing", but we had talked about what we were and came up with we arent hooking up with anyone else and we arent friends with benefits cause its more than that emotionally but we hadnt titled it. So.. one weekend he went to a birthday party and him and some girl kissed, which i didnt hear about just yet and after this party he texted me begging me to pick him up so i did and he was semi drunk and acting very different and kind of pissy which left me confused and pissy too. When i dropped him off he kissed me and apologized for acting that way. The next morning i hear from a girl friend of mine about what he did. He texted me asking why i was mad and he eventually figured it out and admitted that he doesnt deserve me, he's a dick and that we could hangout as friends and its my choice to forgive him when i want. Now we still snapchat and he said he would "do everything he could to make it up to me" but im just not seeing that happen yet. Maybe we've been busy with finals idk. I cant tell if its worth holding onto because a lot of people also recognized that we worked so well together and i loved what we had so advice???
