Depends completely on how you handled the breakup and how her feelings have developed since then, you don't know, she may really miss you, or her feelings of disgust (at being taken advantage of, that the r/ship was just about sex) etc may have grown over time... also depends if she met a new guy etc. SO many variables, but you can't ask her feelings because it will come off needy unless you really know what you're doing. Correct way to handle a breakup IMO is you play it cool, keep your frame as a desirable sexy guy, just say you understand and continue to treat her exactly the same as before -- rewarding investment on her part, not rewarding or getting sucked into drama, contacting her as often as you feel is appropriate to be supportive but not needy, supporting her (including in finding another guy if that's what she wants) without being an emotional dishrag, hanging out with her platonically for a time if that's what she needs, while still using GC techniques to build connection and attraction, but keeping the frequency down so you do not become too available or become her sexless orbiter... continue to sexually flirt, be honest and vulnerable to match her honesty and vulnerability etc, but if she withdraws do not reward it with attention / chasing, just accept her decision and move on to greener pastures. Obviously you may feel jealousy etc, but as a high value man you know this is just your ego speaking (feels un-solid when it loses a part of itself) and rise above it by immersing yourself in your hobbies, work, other social life or FWB etc.
