Physical Intimacy during detachment period

[Mad about Love]

I was referring to intimacy between H and me. I am not looking forward to mess things further with an OP. I also do not believe he has a OP, at least for now or in practice.

I am applying "detach" pretty well now - after going through whole shock/crisis/meltdown period. I have mixed feelings about physical intimacy. There was none basically for the past 8-9 months since he started to change. Since then I guess we did not find time or desire for sex from destroying our relationship.
Now I am thinking that this would make a good 180. But I am sure he will ask for a guarantee that I will not take this as reconciliation... Is it worth the risk of more heart break? Or would it help with the situation? I sense the latter, but who knows... Just questioning myself, and looking any suggestions.
Very very hard times for my family...
