I hope things have improved! My H was pretty similar, he really struggled with the kids gaining independence and not being small children any more. Probably because he was home so little that he missed them growing up. Staying out of their clashes and not taking sides seems sensible. Re the sex, maybe telling him what you need to want to have sex might be more successful than telling him what you find unattractive? Does that make sense? It sounds like he will be too busy to bother with sex or with battling eldest anyway soon! Stay strong xx
