Whether you are the Mom or the Dad: Don't be the one causing the drama.
You have to be better than the other. If she has issues with your new relationship, don't feed into it. If he has issues with your living your life, don't feed into it.
If she's on welfare, refusing to get a job, don't hold back child support.
If he's not paying child support don't keep the child from him.
Drama comes in when you get mad at the other for going on with their lives despite the child, or children you have together. Stop it!
It should never be about the two of you EVER AGAIN now that your child is born!
