Most Helpful Girl
He's acting very weird.Consider how your relationship is with him and ask him if he wouldn't mind if you followed and kept talking to an ex the way he does. To be honest he might still have feelings for her and might not be able to let her go. Do you know why they broke up in the first place? I think that this is very disrespectful to you. The past is the past and he should move on. Have a good talk with him and tell him what bothers you and what's on your mind hopefully you can come to an agreement.
