That it's just built in to them to be like this?
My not so 'D' P acts as if it is fine when I ask him to do something, but then moans about it to others after. He is a master procrastinator - he never finishes anything. He's very hostile and easily upset - if I so much as put a foot wrong he overreacts. He will often then blame it on me. For example he made a joke that was an indirect insult to me (about us not having had sex in ages, even though I'm only just out of the fourth trimester!) and then told me I was the one being crazy as I told him he was being unfair. He constantly thinks the world is against him - he blames his ex for everything. He always has to get the last laugh - can't end an argument with someone else having the final word. He is so sullen literally about 15% of the time (which is a lot in a relationship). He's incredibly stubborn, and ALWAYS late/doing things last minute. He's so confrontational asking things like 'are you being serious?' Or 'are you crazy?' When I have perfectly normal requests. He NEVER forgets (or forgives) when he's been wronged.
He's basically the epitome of passive aggression and I've had enough.
I don't think he does it on purpose. It's who he is and is never going to change.
Do they know they're wrong? Or are some people just like this?
