Hi KGM! I think that qualifies. I'm grumpy toward him too. Not yours, lol (only because he's too far away, likely!) but mine. He is sick of it, too. We have a significantly deteriorated relationship, considering the power that brought us together.

I wouldn't call this depression in the classic sense, but maybe it is? I've certainly thought about talking to my dr about it, but I haven't. I have a new dr., and right now we are dealing w/some health issues (diabetes #1). So I wanted those to even out before moving into this realm, but maybe I should bring it up.
I had a budding career in community forestry before getting preg. and moving away from school, grants, and career to be w/dh full time and be a sahm. It was my choice, and one I don't regret, though I do often wish I'd stuck out at least part time school and finished my phd, or part time work from the get go and had some kind of life for ME. My younger one is now is almost full time school, and I neeeeed to do something productive w/myself. I've been working on some writing, but it's slow going, and I'm very disorganized, so it isn't going all that well.
How old are your kids? It helps a lot when the kids are in school at least part time, but if you are homeschooling, or they are very little (ie: years to go before you get some quiet time), or if you are a type A perfectionist (ie: even if you HAVE quiet time, it's not going to be spent on you, but on finishing cleaning tasks etc.) then it might just be a while!! Sigh.
It's super important to make time for yourself, somehow. At night when dh is home, or on a weekend day when he's around - whenEVER he's around, take a piece of that time and get yourself to the yoga studio! One thing I love about Yoga is that you can do drop in. YAY! Even better, try to coordinate with a friend, double recharge! Coffee before or after, yoga, and some time OFF. And you get to feel like you put some time into your BODY, which I must admit is entirely satisfying when I can do it.

I'm there w/ya mama, and it's great great great that you find ways of not taking the grumpies out on your kids! My kids complain pretty frequently that I'm too grumpy.
