<human>: Hey, so, my girlfriend (21/F) of two and a half years broke up with me (21/M) in the middle of this August. Although she said the words, it was more or less mutual. We were absolute best friends up until the beginning of 2014, then something went whack and we drifted away. We were both pretty torn up for a little bit but we both think the other is an awesome person. Since we are both college students at the same university, I see her often. We talk one-to-one, as friends, on a monthly basis essentially. Since all her friends were my friends first, after the break up, she was relatively friendless. She has two mutual friends that she hangs out with who certainly wanna get in her pants, but she'd never do anything with them (I know I can think that, but I'm serious, she's a 9 and they're awkward and 3s). I'm fairly certain she hasn't "gotten anything" being that she has a limited friend group and would just go to the bars with said two mutual friends. There's always the possibility that she did stuff with random guys who took her home, but I probably would have heard about it from my friends, since they'd be mad :p regardless, would it be a bad idea to try having sex with her again? And if so, how would I even ask? I'm still comfortable around her, she seems to be at ease whenever she sees me, and I feel we're both in some dire need of sex.

Can you give me the gist of the text in a nutshell?
