OP I read something the other day that reminded me of your thread - and that was before the update that he's now texted again. I can't find the link but will try to give you the gist of it, it's going to sound a bit weird but bear with me...
When women are in a relationship with men there is always the possibility of getting pregnant, and that makes us dependent on the man in some way, even when we're using birth control, even when as far as we know we're not actually pregnant - the potential is always there and it influences us in some way, even subconsciously, in terms of how we behave in the relationship both to "keep him" and "keep him sweet".
So when a relationship ends, when is the woman really free? Three to four weeks later, a menstrual cycle, when you know you're definitely not pregnant 
And when do men often come crawling back...?
So often this seems to be the case! It was predicted on your thread too, wasn't it?
Anyway like I said, I know things are complicated and this is simplistic but it resonates with quite a few women, I think!
