Thinking about a haircut

I am thinking about cutting my hair. I really don't want to, but here is the reason why...

I have been working to grow my hair out for well over a year now (basically for 2 years). Here is a picture of me back when Jamie and I first met:

We actually met a few months after this was taken, but it's the closest thing I have to that time. I was all dressed up for a Christmas party.

Anyway, I digress! Here is a picture now (again a few months old, but you get the idea):

The thing that I don't like about my hair now is that there are some long layers, and it's causing the bottom layer to look really thin. I don't have particularly thick hair to begin with, and with these layers mixed in, it just looks even thinner. I would really prefer to have my hair all one length with the possibility of some long, side swept bangs.

So, I am considering cutting a few inches from the bottom to allow the layers to catch up with the longest part of my hair. I hate to give up the length that I've been growing for so long now, but I don't know of any other way to fix this issue.

Any thoughts, opinions, ideas? Should I just leave it alone?? Cut it?? Does it look like crap?? Honesty is much appreciated!
