Stop having a victims mentality! Get of your a$$ and find a lawyer who is going to help you see your kids 50% of the time. That should be your number 1 priority. If you have to file for D file for D. Your W is a horrible human being! She is having an A, toying with your emotions, makes false allegations against you and uses your kids as pawns.
Meanwhile your at home living with mommy. Do you see why she shoes you zero respect? She's got you by the balls and she knows it.
Look man I know that was harsh but I am trying to get you to see what is truly going on. Doesn't mean she won't come around someday. I guarantee it won't happen if you keep doing what you're doing.
