S.P.
One thing that I am glad I did was to put in my divorce decree that he was responsible for his vehicle. I had to co-sign when he got his Audi & when we divorced he wasn't able to refinance to remove my name from the lease. A year later when I went to buy my house, the Audi came up on my credit check and I was able to provide the realtor with a copy of my decree showing I was not responsible for the Audi. Overall, I had a very easy divorce. We didn't own property together or have children, and we remained civil throughout the entire process. As a matter of fact, once we agreed to divorce, we got along great! But I know situations like that are rare; that usually it's a nasty, ongoing fight that hurts a lot of people. I am so sorry you're going through this. Stay strong, reassure your kids that they are loved no matter what and know that you have all kinds of support. One thing I would like to mention, don't use your kids as an audience to vent about their dad. When they ask questions about what's going on, be honest and don't sugarcoat anything but don't make their dad out to be the devil either.
Best of luck to you!
