Am in a similar position myself in terms of having that friendly cohabitation and not being sure whether to withdraw and totally lose any remaining emotional connection or try and maintain the friendliness and contact.
It is so painful not being able to do the simple things, isn't it, just the little kiss, stroke or message.
I have no advice, merely support from someone on a parallel path. Stay strong.
Reality is that which, if you don't believe in it, doesn't go away.
