What to do when your boyfriend thinks your talking to your ex boyfriend?

Tell him to quit being jealous. If you are actually talking to him then say you can still be friends with an ex. If your not talking to your ex then that shows your boyfriend is a little oer protective and controlling. You have the right to talk to anyone you want. Also if your boyfriend doesn't believe that you are not talking to him then maybe your boyfriend has an issue with trust and that's not good for a strong relationship.
