I was in a pretty healthy relationship, and I was actually really satisfied with how things were going. She however didn't feel completely happy because I was too confident for her and it made her feel self-conscious.

We're now just over a month down the line of the break up and there's this girl that I know that absolutely wants to sleep with me (we've had a lot of contact before and I already decided then that she was not girlfriend material), it's just that I feel that if I go through with this and she finds out (this girl is a friend of hers), she herself will also lose all her self control and end up in bed with some random guy, and I still care about her too much to handle that.

 I'm stuck because I do feel lonely and I sure wouldn't mind the company of the "I'll sleep with you"-girl, but I wouldn't want her to lose her self control or even that people think I am a total douche for sleeping with her, since I am considered a pretty nice and trust-able guy by most.

Should I take up on the offer and if no, do you have any tips for what I should do to ease the loneliness?
