<human>: So a long story short about our relationship. We were friends for a year and a half, and now have been dating for a year and a half. She is studying abroad in Spain for 60 days, so far it has been seven. Our relationship is strong and I have never been happier (nor she I hope!) 

So I never dated anyone before her. I never kissed anyone before her. She has all my firsts. Her on the other hand... She has dated other people and kissed other guys. Two notable incidents are (before we dated) drunk made out with my best friend twice and drunk made out with her roommates boyfriends roommate. 

Because of those things (even though it was before we dated) I have this fear of being cheated on. I don't know why! So, for example, she says she is going some place with some girls and going to grab drinks after, I get sick to my stomach for a while imagining a scenario where she cheats on me or drunk kisses some guy and I lose her. 

There is no grounds for this I don't think. I don't tell her because she doesn't deserve to be scrutinized because of my insecurities! How can I just become more trusting because she has been nothing but trustworthy, especially while she studies abroad!?? I think it is rooted in my lack if experience in dating and or any intamicy with the opposite sex before her!

Summarize the given text in a few sentences.
<bot>: I have trust issues for no reason. Struggling to cope with it rather than keep it bottled inside me. Don't want my GF to hear anything about it because she deserves my trust.
