The "sex issue" is so personal for each stitch that I think you will have to be the one to make that decision. For me.....I could not do it. On the other hand, if you read AmyM's thread, you will see where I actually suggested having an affair with her H to try to draw him back into the home again. First of all, they were still legally married, and second of all.... she was madly in love with him and the sexual chemistry was so strong....and she kind of liked that idea instead of throwing in the towell without trying it. But, like she said, even though it was good, it did not help him to overcome the hold the OW had over him. So, since you are a person who needs a lot of phyical affection, it may help "you" to iniate the sex. But let me add this quickly....never do anything if it makes you feel degraded in any way. If he is treating you like dog poop.......don't try to make love to him b/c he could look at that as seeing that he gets sex by treating you badly. Sex should not be a reward nor a punishment, but you do not want to make love to a man that has treated you badly all day or talked ugly to you.
I would just suggest that you work on some other 180's first and see how that goes and how his temperment goes and then maybe you will know if you want to make that step.
Take care, Sandi
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
