My boyfriend and I have been together for 3 years. I just don't feel I can trust him. He has messaged his exes in the past before via facebook, usually when we have fallen out. He always says its to get at me and raise a reaction. He ended up giving me his password as I couldn't trust him after this.
We have recently hit another rocky patch. I was going to block him and try to move on but he talked me round again. We made up yesterday. Today I looked at his account and he had sent a message saying happy birthday to his ex, with a x and a cute emoji. I asked him about it and he said she's a family friend and hes known her forever. To my knowledge, he hasn't wished her happy birthday whilst I have known him or even mentioned her. He didn't see her birthday on facebook a friend told him apparently. I feel like im just being made a fool of, again. Would you feel hurt by this or am I overreacting?
