Ok, so yes, your DP should be providing you with support. That goes without saying. I start crying, my OH drops everything to hug me. Tell me it’s going to be ok. I’m beyond grateful for that.
However, bear with me as I’n going to pick through what you’ve written to try and explain your DP’s behaviour. That doesn’t excuse it, but I find understanding sometimes helps acceptance/finding a way forward.
Ok, so your DP has a waster of a father. Didn’t give a shit, dropped him at a moment’s notice, treated him like an accessory. Didn’t give him any love.
Your DP grew up, I would guess, feeling worthless, without value, like his emotions didn’t matter. Like he didn’t matter.
He learned from a young age that emotions from close, interpersonal relationships were painful and ultimately useless…because what was the point of letting yourself feel if you were just going to hurt?
So, I’m going to hazard a guess that he blocked away the ‘bad’ emotions. Anything negative like fear or pain or shame…because if he lets himself feel those, he’ll feel them with all the intensity of that small boy being hurt by the person he is supposed to trust the most…again.
Unfortunately, letting yourself feel painful emotions is how you develop empathy and compassion. If you never let yourself feel them, you’ll never know how others feel when they’re feeling them.
So his annoyance, flippant comments, his total lack of support sounds like a defence mechanism. If he lets himself feel just once, he’ll have to deal with that childhood trauma, which will be pretty overwhelming.
Like I said, explanation not excuse. He’s an adult. If he wants to develop real, meaningful relationships with anyone, never mind you and the kids, he’ll need to man up and face his past, or he’ll repeat it. Because if you can’t have empathy, you can’t really love.
You need support. You deserve support. He needs a metric fuckton of therapy. Otherwise, I don’t see you getting any emotional support whatsoever from him because he’s incapable at the moment.
