Can I force my ex-wife to get an abortion?
Why do you want your ex-wife to get an abortion?
I don't want to have any children with her.
It's unconscionable for you to try to force your ex-wife to get an abortion. It's her body, and if she doesn't want have an abortion then it's her choice. Forcing someone to undergo a medical procedure that they don't want is completely unacceptable.
She's a slut. I don't care what she wants, I have a right to have children and it's my right to have a child by her.
You should take responsibility for your actions and plan ahead if you do not want anymore children. Tell your wife that you aren't ready to have another child. See how she feels about the matter, and whatever she decides, you should support her.
