I keep a week over week matrix in a notebook for each girl I date. A matrix 7 wide and n weeks long. I find remarkable patterns, in particular days of the week and 3 month patterns. That is, every 3 months things repeat remarkably (or you break up). Other patterns emerge (she only writes to you on weekends, etc). I keep track of what days I text her and what days she initiates (and the ratio). Ideally it is her initiating 2/3 times per week. Last week was actually her best week (4/6).
I'll throw my own pattern I've noticed: Girls initiate texting the most frequently and the most fervently
right before the relationship is terminated--either by her or you. I don't have a notebook, but I'm almost positive that's the case. I think it has something to do with extinction burst--or the branch-swinging instinct (making sure where she stands with you leading up to an impending change in security).
There's a good chance that subconsciously you knew this was it--which is why you ended it first. The stress just got you more in touch with your gut feelings. Even when you act emotionally, or 'incorrectly,' there's a reason you felt those emotions.
I know where you are SUCKS right now--and it will for a while, probably. In the past, I've taken two approaches--One, go for broke. At least you know you saw things through to the end--this would look like what
@Grewd is advocating. PROS: There's no 'what-ifs;' You're acting congruently with your desire; You might be able to get in a couple more lays while she's still emotionally worked-up. CONS: You lose frame (permanently); If it doesn't work, you get double the sting of rejection; If you do get together there's a high chance it's totally on borrowed time and she'll end things on her terms.
The second approach is to--Do Nothing. Relax. You made your move; if she wants you she'll come to you. PROS: You hold frame (if she does come back); You can begin actively pursuing other options (if she doesn't); You maintain a sense of agency. CONS: She might not come back; She might come back but never trust you; She might have to fvck other guys (or even get into a relationship) before she feels secure enough to come back to you--and probably then only for sex.
Or you could try a hybrid approach, which would be to wait a few weeks/months, ask her out, act like nothing ever happened. But I've done that and the results were only ever short term.
Personally, I'd advocate the second approach. Better to stop the bleeding now & get on with your life. I think there's a good chance the emotional relationship has run its course--and you might still be able to position yourself as just the sex guy if you go for the second approach. But you also need to examine your motivations with this girl. I know she's hot, but what would be the reward of locking her down longterm: The validation? Overcoming the ultimate challenge? Beating out the competition? Turning a h0 into an honest woman? Guys don't catch oneitis for bisexual strippers just because she's hot--you could find hotter women at the nearest college campus. More likely there's another dynamic at play that your loss of frame was tied to. Just a thought.
