"I told her that while I thought MC was I good idea, I thought if we communicated more as we were doing now then there would be no need for MC. she agreed." Isn't the MC mainly for better (not necessarily more) communication? Sure you can handle this on your own? Maybe you go to IC thru' your work for help dealing with W and establishing those boundaries, etc.?
"So we are talking more on this theme to see where we go from here. The only let down for me on this part was at bedtime I put my arm around W and her response was to say "how can you go from saying the M is over to wanting to hold me, the turn around is too quick"." She may have a point here.
"She says there is the tendency on my part to try to go for the kill, dive straight into her pants everytime, instead wooing her." Point here too.
"So as Kalni has mentioned she panders to these guys to get the woo factor, they in turn massage her ego and make her feel good and the fantasy builds from there." Like John points out, what is she contributing to the R? Lan, I believe you are taking on too much. She needs to go to therapy to get a few things sorted out or else you will "cycle" for sure. Now is the time to get her to comply, while she wants 'in'.
