Remind yourself that she said you felt like a brother to her. You need to hold back on the sex until she initiates it and you are certain that is what she wants. You will know without "asking" her or getting into a discussion about it. For goodness sake don't get in a R talk.

There are different views about having sex with the wayward spouse and I won't tell you not to have sex, but I would say that afterward......expect her to pull back again. Most of that is a physical need and she may be wanting it also, so in that case.....let her lead, but expect her to fall back into her previous attitude afterwards. Sex doesn't resolve the M problems and is a temporary fix for the physical needs. Do what you feel is right for you, but be prepared for the fallout afterwards.

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!
