We can't control women, we can only control how we show up. I think it's absurd to label the woman as"crazy" with so little information.
The weaker a man is, the more crazy women will seem. If a man is half weak/half strong he'll see less crazy women, but still plenty. A dominant male sees/dates few crazy women because the polarity keeps them sweet and in their feminine.
If you show up the right way, women will not behave the way this woman is towards you. They will be obsessed with you, hit you up all the time, etc.
That said, it sounds like a combination of https://www.musicglue.com/secockpit/
beta-behavior on something keywords tools vs secockpit your part, and a woman who likes you, but not enough to come down off the fence.
Do not contact her. if she contacts you, arrange a meet up. This whole thing just reads as a very infrequent FWB arrangement, except you're in love, and she could care less. You might literally be 3 or 4 down the line on who she calls to fuck, and it sounds like she picks you last. This is remedied by improving bedroom skills.
Who cares what she feels tbh. It hasn't worked (your personal words) and it is time for you to move ahead instead of allow her to occupy space in mind. Some things were not intended to be. Accept things how they are and move forward.
