Slow dancing in a burning room

Fighting. Lately I feel like that's all we've been doing is fighting. Which is unusual, we hardly ever fight usually. People joke that watching is "fight" is the most boring thing ever, because we just don't do it - we bicker but that's as far as it goes. But lately I feel like we're not on the same page. It started with a joke, I guess I carried too far - I was wrong, but I apologized. I don't think he's gotten over it. He's angry, he closes up and doesn't talk about it. Drives me nuts.
Me - I'm a talker. I like to talk it out. I need resolution, but there just isn't any - maybe the thing I need to learn is there doesn't always have to be. Tonight I came home, told him I loved him and he said "ok". I don't know a girl on the planet who wants to hear ok when they tell their man they love them. Needless to say, it didn't go over well - I was upset and let him know. Maybe I'm too needy, maybe I need to hear it every once in awhile - I don't think that's too much to ask. Maybe I just have PMS and am overly sensitive - who knows.
