I'm sure I'm not the only one who hooked up with a girl and just had a hard time getting over it, so I was "dating" this girl, she is 5 y/o older than me and she has 2 kids, but god she was hot, on the weekend after clubbing she asked me if I got condoms, and well, it happened, It was good as far as I can tell, but over the week she told me in a joking/serious way just not to get too into her, since then its been downhill, but I can stop thinking about her.

How have you overcome this type of situation? I genuinely feel used.
