Chalk and Cheese

How the hell can 2 people be so incompatible? I really don't understand what my life lesson should be in this situation, except GET THE FUCK OUT!! Partner-person drives me nuts, and I drive me nuts. I hate the way I can't tolerate a thing he says. I behave so badly, and I'm so embarrassed by the things that I say. I feel like it's all his fault, but he doesn't force me to act the way I do and to say the things I say. I could rather try to just let the stupid fucking words go right over my head, in one ear and out the other, but OMG, I just. can't. tolerate. it.

Tonight's issue was that he says I have no idea how to discipline Little Squirrel, and that I am doing it all wrong. This is all because I threatened to take his toy away if he didn't listen to me, and then when he did his little naughty thing again, I took away his toy. Great follow-through I thought, but oh no. So of course Little Squirrel starts wailing about wanting his dolphin, so Partner-Person freaks about him squealing and crying, and tells him he will go and lock him in his room (I thought this was too much a hardcore version of time-out, so I commented under my breath). Anyway, it got out of hand, and I just hate hate hate it. It's been a while since we have argued in front of the kids, and I swear, I am not going to do it again. I have had enough! My opinion and having the last word should not be more important then the little wide eyes just staring at us.
WTF is wrong with me. I feel like a crap mother, and I just don't want to expose my kids anymore to this conflict.
FFFF!!!!! I'm so pissed off.
