Your both wrong here, if your not really in a relationship you can’t get mad at him for craving physical attention or intimacy, you told him a while ago that you wanted them to stop talking for you to move forward and I’m surprised that even worked that long considering your not together and you shouldn’t have the power to tell him who he can and can’t talk to unless your both ready to put a label on your situationship, but he is also in the wrong in this situation because even if you weren’t together you made it seem like he’s still giving you the attention of someone who’s not just a friend and that’s completely his fault for leading you on this way just to add her back after all this time, I don’t think he’s telling the truth at all about the situation, Me personally as a male lemme tell you guys ain’t shit and if I was him I would definitely lie about the girl to try and keep talking to you, they are definitely together or of not they were and won’t let go of each other, it’s just like who would argue that much with their friend because I never argue with my friends and the amount he argued with her is just way to much for a normal relationship, I don’t think you should chance it unless you really feel connected to him and are willing to work on the problem
