My M is much the same except that I do get some affection. We do hold hands, we hug, she tells me that she loves me. But no sex and no kissing other than the good-bye pecks you mentioned.
Like you, I'm unhappy with it, but after 28 years I've learned to live with it. I'll do fine for a while, then go into a period like I'm in right now where it really gets me down. It'll be this way for a while, then I'll get back into the mindset that there's more good than bad in the relationship and decide that I can live without sex. Maybe that will get easier as I get older.
