How to deal with sulking touchy DH

Relationship counselling - suppose his male pride wouldn't admit to there being a problem anyway!
Talking to him - not going to get very far if he just sulks and give monosyllabic answers.
Get rid - really? Because he's moody? Get a grip. You've already said he has many good points. Would you be happy to see him with someone else, would that make your guts wrench, make you sad?
If you want harmony and fun etc., then join a women's group, go online for friendship only.
You don't say how long you've been putting up with this though.

I was given this piece of advice by a forthright Aussie many years ago when complaining of something similar,
“Wack him about the head with some 4 x 2 once and a while....that should do it!!’
Needless to say I haven’t tried it yet, but please let me know how you get on

I got rid of a long term boyfriend years ago because of this. He would sulk for days on end , giving me the cold shoulder and just yes or no answers. No explanation as to why, and I would spend hours wracking my brains trying to figure out what I had done wrong now. As I was a single parent at the time with an 8 year old, I thought I can't be doing with this anymore - even she doesn't carry on like this, it was like having two children, so bye bye end of relationship
