When Love Is Not Enough

I will be the first person to admit, I'm not the easiest person to get along with. I'm stubborn and impatient. I have been known to run through sprinklers at 3am on the way home from the pub (after having 1 or 2 too many at the pub of course). I drink, I smoke, and I like to go out to the pub. I have very twisted views when it comes to relationships (which I'm sure will eventually find their way into a post of their own).
That being said, I have been in a relationship for the past 9 years and have been married for the last 4 years. As in any relationship there have been good and bad times, he's a nice guy, but I left. I moved out a little more than a month ago, and just this past week I asked him for a divorce. I had been vocal in regards to me not being happy. There were a million factors in play (none of which will find there place here because as I said, he's a nice guy and I would like to remain friends with him and because it's really not all his fault) and I just can't do it anymore.

I think the one thing that really proved to me that us as a couple just couldn't work anymore was when he told me I was not acting like myself lately. he was right, I wasn't acting how he was use to me acting because I was happy. He wasn't use to or recognized the fact that I was happy. I don't entierly blam him for this, I had been miserable for so many reasons for so long that I was a little take by surprise by my new found happiness.

Am I wrong for leaving? I'm sure the answers to that would vary depending on the person asked.
Do I still love him? Absolutly, he will always have a special place in my heart.

So here I am trying to at least salvage a friendship from the remains of our relationship and at the same time trying to tell him that I don't want to be with him anymore.

Isn't it better to end it when you realize it's just not working then to let it drag out until you end up despising each other?
