OP,
I can't do anything but speculate, but if she's gone cold after you've had sex with her a few times, maybe you need to work on your f*uck game. Seriously. Might be tough to hear/read but could be the truth.
Some of your posts lead me to think you may also be "too nice" which most all women are just not attracted to. Telling a girl how much you like her early on is NEVER a good idea and a BAD mistake. I know it sounds counter productive, but just accept it as Boys and Girls 101. Women want (even subconsciously) a man who is a challenge and by placating to her, you're not a challenge to her at all. The man who can walk at any time, and has options, is actually very attractive to a woman at the primordial level. Chasing, acting needy, asking what's wrong, and too much checking in only works on Disney and in RomComs.
If it were me, and it probably was many years ago, knowing what I know now, I would:
- Back off 100% and go total NC. She wants you to lead, as some have posted, and you have tried, but she said she's busy, the entire week. Bad sign. A woman who is into a man will move heaven and earth to see him. Ask some of the female posters on SS.
- Work some of my other plates
- Start over. Here is a principle that isn't talked about enough on SS: It's always easier to start over with someone new than to try and undo beta behavior and a bad situation (loss of power balance or "hand") with a current woman.
Good luck.
