We met when she went to my town (she lives in another state) and we ended up spending two nights together. (She's 24 and I'm 20, dunno if it matters)

After the 2nd time we slept together, she told me she'd been in a relationship for 7 years, and was going to spend Christmas and New Year with her bf on another town. I kinda said "yeah, whatever" cause I didn't want to upset her nor wanted her to leave, we talked and laughed for hours after this. She then left but we still texted whenever she had some time away from him.

Thing is I'm really into her and it seems to go both ways, we talk nearly every day now and the time we spent together was just great, so are our conversations. Just knowing she'll be back in a few months made me feel great.

Except I feel like a total dick for going through with this, I've had a long relationship myself and I'd be sick to my stomach if I ever found out I was being cheated on and she had kept in touch with the guy (most of our texts are pretty intimate, almost like we're in a relationship ourselves). I sometimes forget she's not single and whenever it hits me during our talks it makes me feel like a total douche.
