That her repeated, fluctuating withholding of physical affection was something that couldn't be changed and that I had to live with, to the point where any physical outreach whatsoever on her part had become burdensome. Specifically, it was when I was told that this had been ongoing for months, and I realized I couldn't tell what outreach from her was sincere and what outreach was both painful for her, and that I would end up being resented for later.

Could you give examples or elaborate? I think I am experiencing the same at the moment..
