<human>: I want to start a relationship with a relatively good friend of mine, who I believe in the past may have had a thing for me, but I didnt realize it. Anyways now shes all I think about. I feel she likes some of our mutual friends alot more than me, but as far as I can tell I dont think they like her. That being said, I think she might, just might still have a thing for me but I really dont know. I found out she slept with another friend of mine, and they both know that I know about this. I dont think the guy wants to date her though, although I can tell she likes him quite a bit. 
Anyways, I want to ask her out, even though I know she'll probably reject me. Do you think I should?

Give me a shortened version of the text
<bot>: I like a girl whom Im friends with, who probably likes someone else, but I feel they dont like her, and would just use her for sex. Should I ask her out?
