Saw disturbing messages on boyfriends Facebook, what do I do?

[Teresa]

After a relationship of three years there should be open communication between a couple. Yes, everyone is entitled to their privacy but entering a relationship should come with a mutual understanding that keeping hurtful secrets is not ok. It should be of some concern that there is talk of meeting and having a physical relationship. That is uncharacteristic of love or commitment in a relationship. He may possibly feel that there is something lacking in his relationship with you but if he is unable to communicate that with you then he has no concern for your feelings. I would ask him about where he stands as far as your relationship goes and even inquire about his happiness or insecurities. Give him a chance to open up. If he chooses not to do so then i would say you need to confront him directly with what you saw.
