So my girlfriend lied about her ex. When we were at our talking stages see claimed that she didn’t talk to anyone the way she talked to me. But I recently found out she was telling her ex that I was nothing to her, and she would even have me under the impression that she was asleep while she was talking to other guys.

We are now together but I am finding all of this out now. I always suspected her ex but she told me a lie, and now I found out the truth and it wasn’t through her. I really like her but know I feel like I cannot trust her like I used to. What should I do?
