Is there a root cause of why he doesn't trust you anymore all of a sudden. Maybe he is not trustworthy so he projects that on you. I am don't know it is a suggestion. I don't know your situation, but I am sad for you because my wife cheated on me after 12 years of marraige. If there was/is not infidelity then can you try and work things out. People change that is one of the reason I don't get the whole marraige thing what is the point?
I know I am not doing it again and I am not going to encourage my son to get married. I am going to tell him all the ways he will get screwed.
Anyways I am sorry you are going through this but you did love this man at one time. Please change my thought of marriage and try and work this out.
Just my suggestion.
