<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm (24) afraid my girlfriend (22) finds it easy to lie to me. I'm in medical school and she's in law school. She says that she's attending all her classes and taking her studying seriously but I know for a fact that she's working instead.

We started dating through a mutual friend and I really do love this girl and things have mostly been very good. We've been together for about 8 months. The mutual friend (girl) is in med school with me and once when we were out partying she told that my girlfriend can be a bit difficult and has had some past mental problems.

My girlfriend has told me that she has had these problems (mainly anxiety and depression) but what our mutual friend said made it sound a lot more dramatic.

I'm no snob and I've told her that if she doesn't want to be in law school she should do what she wants to do (she's working at an event planner and she really likes it) but she insists that she wants to be in law school. We've talked about this many times because I've told her that I think she works too much and she doesn't focus enough on her studying. I've told her if she doesn't like it she should just quit but she says she wants to do it.

The reason I know she's lying about attending her classes is that I can log into her email through our computer (I know this is a HUGE dick move and I obviously have trust issues with her) and have seen her sending emails constantly when she tells me that she's in class. I've never confronted her about this because then I would have to admit the way I got the information.

I know this is not a lot of information but I was wandering what your take is on this. The thing that bugs me the most is that she finds it so easy too tell lies about what she does during the day and what other things could she be lying about. Please help me.
<bot>: My[M24] girlfriend[F22] of 8 months is lying about what she does during the day. I have started having trust issues with her because of it. Help me.
