I basically feel guilty for filing for child support.
Child support is for the kids not for you. I completely understand why you might feel guilty, but you need to put it into perspective.
Your sitch is so similar to mine and I feel for what you are going through. Right now I am in a very terrified state of mind and I am trying to work through it, so I don't have too much advice to give, except that there will be a light at the other side of this. I truly believe that, and I see it in those who have already made it to the other side.
Get a lawyer and protect yourself and your children. He is going to try to guilt you and blame you and make you feel like you are the one who did this, but they are all tactics. Just because you get a lawyer doesn't mean you have to pursue, all it means is that someone is watching your back when your emotions keep you from seeing the bigger picture.
