Cherry, just got a little caught up with you. I can speak from my experience, beware the pendulum swing.
I feel like the sex my H and I had at the end of our S lead into piecing, or was a major paver...we did start connecting again and there was love in his eyes...but. One day he put his wedding ring on again, and I really wish he hadn't now.
If their heart is following along out of guilt, duty, or whatever else and isn't leading...idk. Idk if sex is a bad idea IF you can stay detached and not try to read too much into it. It just seemed there was a big recoil out of it all. But I do know it moved the situation.
Not trying to hijack, just sharing in case it's useful.
