OK, the part about not being attracted to you etc. is part of the script. My W has used this line a number of times, mainly when I was needy, to get me to go away. Don't panic. Have a look through my sitch (there is ten parts so far!) and you will see how I have been through a lot of the things you're going through now.
We're separated, but still in the same house. My W has shown signs of wanting back, then got scared, and it starts all over again. Some of this is my fault, as I have maybe shown too much enthusiasm etc.
Yes, pulling back whilst in the same house is difficult. I get you. At the minute you're scared of losing your W, family etc. This is the difficult bit. You have to get over the fear of D. That is going to take you weeks. It's not easy to do, and you will make mistakes. The important thing is to apply Sandi2's rules and really, really, detach.
I'll check in to see how you're doing.
