I feel like I write a post on this sub every other month. So three weeks ago one of my close friends broke up with his gf of over one year and long story short she was really trying to hook up with me this Friday. I rejected her and told her this can't happen to her face, however later I drank more and she came up to me again and we hooked up. I feel guilty. So:

  1. Do i tell my friend about it and apologise?

Or

  1. I don't tell him anything and act as if nothing happend.

To make thing clear if she was not my friends ex i'd probably want to bang her, but well the situation is a little more complicated.
