My boyfriend and I broke up and...?

broke up on Monday and I miss him dearly. We dated for a month and we were happy together aside from fighting alot and me not trusting him. It was weird the way he treated me. He would act like I wasnt around when he was around his friends. That pissed me off. We were always happy together but when we were around other people it ruined us.. We were amazing alone. Our relationship went fast and we had the 2nd week of dating.We show PDA but i told him sometimes i feel uncomfortable. Well to the point, I broke up with him because he lied. He lied about were he was one friday. He was with has guy friends hanging out with girls. I asked him why he lied and he said I wouldve have been pissed. I told him that was BS. well i broke it off instantly after the fight and didnt think it over. He lied to be about a bunch of other things too,so i got fed up. But now i miss him so much! ive been crying alot. i have 2cles with him, but we dont talk. we also have mutual friends but he doesnt come over and talk at all. i think he is scared cause everyone told me he was.. Idk if he has moved on cause he was known to be a player. But should i talk to him or leave it alone?
