To think he's just not that nice?

[whatchadoing]

DH that is.

He's hardly friendly towards me. Gets frustrated with the kids like five minutes after he gets home from work. Is getting more and more negative as he gets older.

I want a happier partnership.

Financial stress?
Physical ill health?
Work related stress?

Have you actually sat down and spoken to him?

Have you asked him what's going on?

You know him best, so you are probably right. We are all people who have never actually met him.

It isn't a case of "not being nice", for whatever reason he isn't engaging in your relationship or Family life.

It's now about finding out the reason.

You're going to have to ask him outright and make it clear that things need to change.

He will mutter and swear under his breath. Then pretend he didn't say anything.
It might not sound like much but it happens all the time.
