Hi Tmutchlove
Welcome.
Those are some confusing messages from this person.
Being cheated on can be a very painful thing. Are you alright? I've had this sort of thing from my relationship, and I also got what I think is generally a "he's harmless so let me stay in touch with him" type of description from my partner. That happened a few times. What helped me was to validate my own feelings around the issue and think more about what was important to me regarding fidelity.
The up and down you describe is familiar to me, and I don't doubt it's the same for many others here. I moved to predicting cycles so I could plan my weeks better--that's similar to your thoughts on her "cycle" in November.
I suggest you have a look at the surviving confrontation part of this board:

I hope you find peace.
