I've been with my girlfriend for close to 4 years now, and in that time we built what I thought was the most emotionally significant relationship I have ever been in. We did sperate around Christmas over some mutual things, but reconnected after new years. During that time she lied to me about an interaction she had while we were separated, which wouldn't have been a big deal in the first place because we were broken up. After putting her in some situations where she thought I was going to find out information on my own she confessed to sending feet pics to someone (this story has a lot of nuance) she confessed to lying about sleeping with a guy before we met, which also wouldn't have ever been an issue. But there was a lot of negative involvement with this guy throughout our entire relationship, so we talked about him and the situation endlessly but she continuously denied sleeping with him and often included that he lied to a lot of people about them sleeping together. She also confessed to at some point attempting to rebuild her relationship with her ex husband, and has given very limited information about what went on with that. This story could go on forever, but the short of the long is that she claims there's nothing more to tell, but really only confessed these things out of fear of me seeking information outside of her. Obviously there is more to all of this, but I don't think I'm going to get any more info, so I don't know what to do. Anyone been in a situation like this, and have any advice?
