puzzled?

i just broke up with my girlfriend of a year and im worried i did the wrong thing because I feel so gutted, would appreciate some advice? Basically my concerns about some of the ways my girlfriend behaved towards our relationship and the complications that seemed to follow her pushed me to take action. Her job involves her living away so we don't see each other a lot, however I have noticed I here from her more when she is lonely and away, when she returns I don't feel she gives our relationship as much attention as she should.
Over the past few months I have noticed her ex contacting her a lot, he speaks to her in a way that suggest they are more than friends, this bothers me and she knows it, still the contact remains strong. I would probably give her the benefit of the doubt but I have discovered she has kept a lot of romantic emails and texts from him (apparently she likes to keep memories) she also recently just moved in with her ex's best friend but failed to tell me (apparently she knew it would hurt me) I have not been introduced to her family yet , but she has suggested, and has met mine countless times. I recently discovered she has lied to me and others quite in-depth about a designer item she purchased, she doesn't know I know its fake but she seems to have convinced her self other wise, this leads me to worry if she lives in denial about something like this, is she telling lies about other things such as the kept emails/texts, does she still have feelings for her ex? I cant help feeling a lack of commitment on her part.
