<human>: So to start it off, we have been in a long distance relationship for about 2 years and I myself have always been shy and  introverted lifestyle. I have told her this quite a few times because I know how bad it gets when i am insecure about things, but she has never really made the notion of fully cheating on me. She has guy friends and I'm not insecure enough to where her having them hits me wierd, but one in particular is consistently flirting with her whenever they have conversations.

She mostly ignores it which makes me feel like either she is doing that because she knows im able to see the conversations or because she doesn't actually plan on doing anything with him. More than anything im just more scared about bringing it up because I don't  want to break up with her but I don't feel comfortable in a relationship where I'm not certain if my partner could possibly be cheating.

Can you condense the text into a few key points?
<bot>: I'm not sure if my girlfriend is cheating on me and I'm to afraid to ask, any advice on what i should do?
