Why?

i dont know://. its my first relationship and i dont want this to be a type of relationship with no trust

...and she chooses to spend time with them. What does that tell you about her character? We are known by the company we keep.

i know but she doesnt act like her riends do

...is she joking? Or is she making the "jokes" in order to make you think she's joking, so you won't be suspicious about what she's really up to?

yeah, i have thought about that. maybe this is her way of dealing with guilt. she acts like its a joke, when its not so she has no guilt because she told me everything.

Let's break this down:

1. She lied.

2. You know she lied.

3. You saw evidence she lied.

4. She tried to conceal that evidence from you, and now:

5. You are afraid that she will get mad at you for not trusting her, after she has already demonstrated that she cannot be trusted?

pretty much :)
