BPD. I know you are feeling like this is a step toward R but more than likely it is not. In fact, you may have taken a step backwards as you just firmly established that you are a solid Plan B. You may have also just reminded her that she isn’t “in love” . Sorry. I know that isn’t what you want to hear. The reason she wanted to have sex after no affection for six months likely has nothing to do with her wanting to R.

What should you do next? IMO...nothing. There is nothing YOU can do. The ball is in her court. She needs to fix whatever is broken inside of her and then maybe you can work on the marriage.

I don’t mean to sound harsh. I am just concerned that you are setting yourself up for more disappointment. (((HUGS)))
