Your W sounds a lot like me. I have very severe intimacy issues culminating in my inability to be loving or openly sexual with a man unless he is rejecting me. This is probably the reason I keep dumping my H--so that I can feel attracted to him. It's a nightmare for me but worse for him. Although I remain in the marital home I am the WAS who is also probably in MLC. I have had numerous EAs.
One of the other issues I have is the constant flux of changing emotions and it results in me doing a start/stop pattern on my poor suffering H. It truly is a roller coaster.
I believe these problems were most likely caused by childhood sexual abuse but I don't have direct memories of it. Just my intuition.
I have dragged my H to 3 counselors but in all honesty I think I am the one who really needs more intensive help.
