It sounds like you already know what to do and what you want to do.

before my 2nd husband and I split up, I wavered over the decision for about a year. I was worried about finances and about him blowing up and making it horrible. All it took to put it into perspective for me was thinking of my two kids and them approaching high school, knowing I would only have them at home a few more years and wanting something better for them. I have never regretted the divorce.

I wish you strength and courage.
