That is interesting OTW. My case is actually similar. When we were younger, I literally pretended I wanted nothing to do her though I did. She was really infatuated with me then. Fast forward, 3 years and that was over. Then it was on and off for a while. Then I said that was it, no more, I stopped given her the time of day. 4 months later shes back. The that ended and we were off for about 4 years but I still talked to her waaaay too much. She got a new bf, and I said fine, that's it. I went no contact for about a year, actually very similar to the state I am in now. Then all of the sudden she started pursing like crazy and we were back together, eventually getting married. That lasted 6 years. I guess I had given in to easy every time.

This is why sometimes I question if this is worth it. I do want to be with her, but the pattern is too consistent. I have to figure out how to break it.
