My boyfriend of 3 years and I are having problems. We were seeing each other for a few weeks when he went away and slept with another girl. I understand we weren't officially together but I only found out today, 3 years later. I am upset he cheated and hid it from me, do I have a right to be? Also he had done a lot of nasty hurtful things on dating sites but swears he never met anyone. The last 10 months we have been trying on our relationship but I am so hurt I can't stop talking about it or accusing him.. he has been going to counselling and has been emotional because he is trying to show me he has changed and this is the person he will always be.. I find it hard to believe. I love him and can't bring myself to leave but do people really change? I do admit though, he has been trying very hard but just finds it hard to tell me things as he is embarrassed. I'm hurting :(
