My Boyfriend and I broke up a week ago because we might need to deal with long distance relationship (6 months). We discussed and talked in person he was really nice I cried so did he and said "I didnt want to end like this". We agreed to talk as friends but he has been acting cold and distant to me. I decided to stop talking to him for 5 days now. And last night I just recieved an instagram message from a girl saying my ex has been sending her kisses and said that me and him broke up.... (She sent it to me 2 days after we broke up but I only just opened it) .Also during the weekend he was the first person to watch my snapchat stories (I post like every 2 hours). I know that he rarely check snapchats because he is not bothered.I am shocked and I nearly send the message that the girl sent me to him but so glad that I didn't. Im confused about him...was he cheating on me or getting a rebound? Why is he ignoring me? What should I do?
