My boyfreind says that he is at the end of his rope with my emotional freak outs. I feel very abandoned by him a lot of the time when he is late or doesnt' call me. So I get really angry and yell and cry and otherwise blame and get upset. I have trouble controlling this and it says it pushes him further away from him. How can I control myself and my emotions? I've tried calmly telling him that I want him to communicate more when he is going to be late or don't be afraid to call me if he needs to change plans, but he doesn't call to change plans because he doesn't want to hear me freak out. I just want to be ok so I can hold a normal relationship. Any advice?
