WOMAN! This must be yelled. :-)

I acknowledge that you were hurt and this is not to be taken lightly. And you describe it well.

But don't give up though. Many guys deal with women feeling like you do now and the ache for the chance to be let in.

Don't let them all in, and I'm sorry for your pain, but you did right when opening up.

Well written. Would maybe have used some smaller paragraphs instead of just one big one, but I think there's a good flow and the point is easy to find and so is the hurt.
