chicki, it will defintately cause a lot of confusion, H will be balancing the scales. The more romantic and intimate the sexual relationship is the more drawn H will be to you. In all, the R will be rebuilding and H has nothing to lose since he will have both you and the kids.
All H has to lose at the moment is the R with OW since he probably isnt an integral factor in OW's R with her kids.
Keep it up!!!
See the W, Listen to the W, but dont Speak back to the W. Bridle your tongue...
