I told my girlfriend who said she needed more 'time' that we should go no contact, that was on Monday. But there are 2 questions that are driving me mad that if I don't find out I think will always drive me mad.
1. What did I do that made her so unhappy?
2. Is there another guy in her life?

What should I do.. should I call her and get these questions sorted before I do NC what do you think..

p.s. the reason she said she needs more time is because she thinks I don't care about her like I used too (see my other post for details).

I believe you are playing tricks with yourself; I have done the same thing. You are not responsible for what is unhappy in her life, she is. If there is another guy in her life, there is nothing you can do about it. Take one day at a time, and read the other posts on here about getting dumped. And, read them again.

Don't matter what the answers are, and what good will it do. If you are going to move on with your life, just do that.

If you ask these, next week it will be something else, then another question and another latter.
