So update, and hopefully last one with my friend and his lady.
He told her the details and she denied everything completely, saying she was singing along to a song and I misheard her. Which is complete bullshit because she thought she was singing Nails' song Closer to me, (which even if she was her "lyrics" were completely off) but that song was later in the night. I even went on to tell her the other crazy sexual shit she told me and she denied everything saying that it doesnt make sense and Im mistaken. Once again, denies complete responsibility for her actions and throws it on me. Well..What did I expect from her? To man up to her drunken stupidity? Sadly, yes.
In anycase, hope none of you ever have to deal with a situation like this because it really makes me want to punch her fucking face in, and I never ever have gotten to that point with a woman.
Things are cool with me and my friend, but things are never going to be the same between me and his lady again.
