I just read your other thread. In your first post, you mentioned that you suspected he was in an R with someone else. If so, then I would not have sex with him.
However, if he's not seeing someone else, then I would consider it for the same reasons you mention. (In fact, I am maintaining a sexual R with my H for many of the same reasons.)
You have to be careful though. He is telling you not to have any expectations. While that may simply be a protective statement on his part, I would not get too wrapped up in the idea that sex = reconciliation, for your own emotional well-being and for the sake of the R.
MWD has an article about this very topic. I couldn't find it on the website or I would have linked to it here. But if you search the forums, you will find it. (I think that's how I stumbled upon it a few months ago.)
