I feel that my inability to keep my emotions intact is hurting my relationship. It is not like I am yelling and screaming at my boyfriend when something goes wrong. It is more like I feel like I am unable to control my thoughts when something veers off course (e.g. he cancels plans when we had them and this leads me to think he is hanging out with someone else) and this is what is pushing me to do something that I regret later. I think I may have slight trust issues that may have lingered on from when he lied to me at the beginning of our relationship, but I have told myself to put that behind us. I feel absolutely terrible when I do this and feel that it is some sort of mental issue or there is just something I need to do to control myself. Any advice?
