First off, we're both tired, sleep deprived and have MH issues. He has physical health issues also but uses these as reasons to be mad a lot. We have a four week old baby and are still adjusting. I had an awful birth and am still healing.
Starts off with DC needing a nappy change. I hand DC to DP, saying I'd done every change so far today so he could do this one. He complains a bit but starts doing it. I then remember one of our pets needs medication and 1 - sitting on the floor hurts still, and 2 - I'm absolutely exhausted. So I ask him if he can do it. He says as he's halfway through the change no. I say I'll take over, can he please just do it. He gets very pissy, saying I just don't want to and that he has to do everything. DC then weed mid-change. DP stomps off, leaving DC on the changing table (waist height) in their own pee. I'm the other end of the room. I obviously go straight over, especially as DC is already very into rolling. I finish up the change, do a feed and story and get DC settled. DP had the whole time of this to come and speak to me but just sits there. After DC is settled I go to speak to DP as I'm fuming. I tell him he left DC unsafe, in harms way and it was completely unacceptable. His reasoning? Because he was pissed at me and DC didn't roll off it was fine. I then asked how am I meant to trust him around DC, he replies that I shouldn't make him pissed at me. I then had to walk away but said very plainly that he didn't deserve to be our child's dad, and that to stop being pissed at me/animal responsibilities he should just leave.
So, AIBU for 1 - being absolutely disgusted and fuming? and 2 - for saying what I said?
Also, he is still on leave so him helping with things isn't on top of work.
