The strategy I'm trying to take right now is, let her do her thing, and I'll do my thing. Let's act separated.
So is coming on to her something that is part of the separation?
You can call it a 180 if you want, but to me, it sounds like you are hoping that being physical will ignite some kind of 'spark' in her. I dont think that will work.
Also, did you ask about STDs before trying to sleep with her?
