So, despite everything I've been through so far this year, it appears that fate is kind to me and is looking out for me. The girl I was supposed to go out with originally backed out for whatever reason (still unclear to me).
The friend that set the date up found me another possibility (before I had a chance to think about the advice here). I've started talking to her. She has moral issues about dating someone who is still technically married.
I find myself in a comfortable situation. I have a pretty firm "don't talk to two girls at the same time" rule, so I don't feel the need to keep looking. Divorce is still months out, so I have time to work on me, and to heal, and not worry about rebounding or whatever. I have my proof that I can still attract someone so my ego is satisfied.
I'm genuinely content if she ends up as JUST a friend going forward. I don't feel the need to rush anything.
