Broken relationship

My boyfriend and I have been together for a long time, but we have always had some issues. It all started when I cheated, I was young and dumb and if I could go back I would fix everything. After a year of dating we got engaged and about 7 months later I found out I was pregnant. We lost the baby, and then I moved out and we broke up. We just got back together but we are having issues well he is having issues with me trusting me and stuff like that. What do I do?

Is he still experiencing issues despite your having taken real steps to make amends and keep him reassured? Why did you move out after losing the baby (his, I take it?)?
