I want to ask my ex to consider signing over all her rights to my current wife. Do you think this is valid of me to decide on?
I can't really get into this logic, do you want that really for your ex after you treated her so poorly? Why do you want her to sign over rights?
She's a cunt and I've had enough of her
You finally want all of your ex's rights stripped away from her concerning you now that you are married again, but you called her a very awful name. Be more kind and you can still give the rights to your wife which she does deserve. Waiting so long to do it just made your ex feel superior to her, never do that again.
No I'm a jerk and I hate her.
Well, the name calling is what bothers me. Just have a formal discussion with your ex explaining things as you have remarried and it's time to move on. Leave out the nasty name calling.
