<human>: Currently in college, met this girl who lived in the apartment down the hall from me.  We hooked up one drunken night and then continued to do that for a few weeks until we started hooking up when we were sober.  It eventually blossomed into a relationship.

I have only had one girlfriend before her in high school, for about 2 years, it ended terribly and we no longer speak and never will again.  She's also the only other girl i've had sex with.

My girlfriend had a bunch of boyfriends throughout high school but only slept with one of them.  She had some one night stands during her freshman year and before we hooked up during this year.  

When i asked her about her history, she told me what i said above and that she has had sex with "more than 5 but less than 10" guys but didn't have an exact number.  She also said I am the best she's had and that she had sex with me way more than with everyone else combined.  

My problem is that I can't really get over that she's done that.  We fought about it a lot in the beginning of our relationship, but I can't seem to get over it, even though I have been acting like I don't care anymore.  She also told me she has intermittent FB contact with her ex, and I don't really feel comfortable with that, especially now that were on summer break and I am not geographically that close to her.

She says she loves me and hasn't felt like this with anyone else before and hasn't been with someone for this long before.  I want to accept and feel comfortable with her past, but I dont know how.  I feel like i cant trust her as much as I want to because of what shes done.  Is this trust misplaced? Maybe its hard for me to understand because I've never had a 1 night stand or anything.  

Advice, comments, anything!!

Could you distill the essence of the text into 1-3 sentences?
