I've tried so hard to keep my kids
Fighting for you kids should be your #1 priority.
Yes, I have always liked kids and I want mine back.
You are a good parent for fighting to keep your kids. While many people don't want the responsibility of taking care of their own child, you are doing want is right as a parent and I believe a lot of people respect what you are doing. If you didn't fight for them people will think you are a deadbeat parent.
I want kids so bad. My ex-husband doesn't want them. Well, he wants them but he doesn't want me to have them.
You should just keep fighting if you really want to keep your kids. It seems like the respectable thing to do in this case, so good for you!
