<human>: I'm having a problem with my boyfriend. He keeps bringing up his ex-girlfriend and is very possessive. What should I do?
<bot>: It sounds like your boyfriend may have some unresolved issues around the breakup of his relationship, and you might want to consider talking to him about it. Ask him if he would be willing to talk through what happened in his previous relationship, and listen to what he has to say. You could also suggest that he get counseling or therapy for this issue.
