Me and my SO have been dating for almost 6 months now. He always brings up his girlfriends and sometimes flips out on me for no reason. I thought we were great and happy with eachother. But then a couple of weeks ago i found out that he posted a picture on this dating site of him shirtless and i dont think im over reacting because i gave him the chance to tell me the truth and then he tried to lie. Now hes saying that we need some space sometimes because we live together and that if i dont stop fighting with him that he doesnt see us going anywhere.. i feel like he doesnt want to be with me but he doesnt want to hurt me.. what do you guys think?
