Hey Dez - I just got caught up on your weekend from hell. I'm so sorry you had to go through that!
I agree with was has been said so far and that it is a great idea for you to seek some counseling for you.
I would also suggest writing him a letter (or novel) detailing what YOU feel is wrong in your relationship, how he makes you feel, and how hard this past week was on you.
DH and I had a lot of problems right before we got engaged, basically a fish or cut bait situation. I wrote him "the Mean Letter" that he still refers to, going on 2 years later. It really helped us because I am a festerer and never told him my feelings. He is from a yelling family and I learned that I have to yell to get him to hear what I am saying. It might be brutal but is does get things out into the open. I'll e-mail you a copy of my letter if you want. Even if you don't send it/give it to him, I promise you will feel better.
Good luck, in whatever you decide to do. Big Hugs!
