My DH has always had a temper but only when it comes to minor inconveniences and inanimate objects. It's bizarre.
For example just now he's shouting and cursing at a pump he's using to inflate a pool and when I've asked him to stop he's gotten cross at me. I told him I'd do it because he was taking the good out of it (first paddling pool for our first child) he's told me he is doing it and sent me to look for another pump. I'm looking after a 5 month old so I haven't bothered.
Other recent examples are cursing loudly when food falls off his fork, his phone/telly etc not working exactly as he'd like.
This issue has long irritated me. It triggers me back to my very angry and strict mother when I was a child. I've raised it in therapy and learned ways not to react to the trigger but to be honest it gives me major ick and I want him to stop it. I've been asking him to address it for years. I'm also worried that it could affect the baby and I don't want him growing up afraid of a parent like I was (as was DH).
He's pretty good other than this.
Do I insist on therapy? Ask nicely again? Remind him how it bothers me? The usual response is that he'll acknowledge what he did and apologise but never actually take steps to stop it happening again.
