(First I know nothing of this disorder and know no one who has it)So I met this girl through FB and we started messaging, which led to us eventually meeting up, I noticed she was smiley and giggly and I made her laugh a lot, which was great, we had a wonderful evening and at the end of the night it led to some foreplay (nothing happened Cause we were in a busy parking lot). We met up again recently and went to a bar and came back to my place and had sex, a lot. 

We message and talk to each-other every day pretty much all day and I really like her. She told me today she was at the pharmacy for medicine, I asked “what for are you okay?” And she said it’s for her bipolar. I was reading that this condition makes you more likely to cheat on your SO, and be hypersexual, which is probably why she has been so sexual towards me and she even said “I’m a horndog I think of sex so much, especially with you” 

sooo now I’m worried, she’s going on a trip in another state to a concert with her friend who has 2 male roommates and she’s taking a couple friends with her. I feel heartbroken and sad and am now thinking that we will not last because she may cheat, as someone whose been cheated on in past relationships I don’t know if I can do this. I just want more information is all I guess.
