Good job, I didn't do the same as you did. I was not as strong, I made the mistake of taking, no it's wasn't a mistake, I have a son who is 8 now he has ADHD, OCD and seizers. Long story short. I had to do the same thing you did only with my son. He has, I think, 3 children none are with him or their mothers and he has another one on the way but she broke up with him. 2 children are with one girl and the other 2 are with 2 different girls. It's too bad he doesn't have insurance I told him he needs to get fixed. I have his first and the other two were adopted. I don't now what the mother of his next child is going to due.
I made him and his girlfreind, the mother of his first child, leave my home in the middle of winter with 6" of snow. I gave him enought money for a hotel, told him not to take his son and if he had a problem with that to call children and youth. The mother would not sign the adoption papers until we told her we would be getting support from her. The papers were in the lawyers office the next day, yes the next day.
I could go on and on, about my sister and the rest of my family, but I just wanted you to know you are not alone. Maybe I should write a book. Take care and God Bless you.
