Ready to pull my hair out...

Yes... it stresses me out THAT much. I always go back and forth about whether or not to grow out my hair. I'll cut it super short then a few months later say I'm growing it out. So it'll get to about my shoulders (after a year of cutting it as it grows out so I don't have a mullet) and then I'll get sick of it again, and its back to being short. At this moment, my hair consumes much of my thoughts when I'm not with Noah (so basically all of my free time). Its pretty short right now and I would love to go much shorter; SO... the other day I was looking for short hair cuts and came across THIS BLOG and its something I should NOT have read. Some of you may know that Sienna Millers short hair cut is what I have now... so the thoughts that came to mind when I read this are:
"Is my husband lying to me when he says he likes my hair short?"
"Am I the same person he married?"
"I should just grow my hair out."
"Maybe men really don't like short hair and Jordan is just being nice!"
"AHHH! What did I do?!?"
...and so on. Complete self doubt and crushed confidence. The thing is, I absolutely LOVE short hair. I think it looks much better on me than long hair does (the longer hair I had a few months ago, I feel, made my face look chubby). I think it really takes a confidant person to cut their hair super short. But I just don't know what to do.

Have you ever watched Desperate Housewives? There is an episode where Lynette (who has cancer) buys all these different wigs and her husband loves it. Its a pretty funny episode. But after asking Jordan (for the trillionth time) what I should do with my hair, he suggested I just shave my head and buy a bunch of different wigs. Then I would NEVER get bored... Right?
