Did she file for divorce because you cheated on her?

OP - did you remarry someone much younger? Better looking? Without kids?

The ex (even if she initiated the divorce) is feeling jealous that you're starting a new chapter. Especially if she isn't with a new guy. And you end up having more kids with wife #2.

If you have been less than 100% perfect about child support and parenting issues, you have only yourself to blame.

She is trying to lock in a higher amount to make sure she still gets enough after you have more kids. It happens a lot and she is not crazy for doing it. You should have expected this.

Because sometimes the new wife is unkind to the children or comes between them and their father. Or has more kids and then the man is not able to adequately parent them all or hold up his end of the deal logistically. And it's just another person to deal with. You are disrupting the established arrangement and nobody knows whether it will be better or worse for the kids.

It is a cliche for a man to get remarried to a new, expensive second wife who expects to be lavished with nice things while the kids/first wife get the shaft.

I don’t know anything about your situation (I’m sure your bride is lovely and frugal), but I could see that being your ex’s concern.

Does your fiancée have her own money/career? What is your age gap?

your subject line says the anger is about your new wife. Your op says your ex is "alleging all sorts of things." Are the things she's alleging about your new wife? Is she worried about your children's well being when around your new wife?

Not saying she's justified, just asking.

Your ex is a mean, vindictive troll who hates to see you happy.

Enjoy your new life, and forget about her. Let her wallow in her hatred while you ignore her.

Good luck and congrats

Sounds like my husbands ex-wife. She filed for more child support based off my income. She was horrible to the kids and stopped visitation. The courts were a joke. Hope you have a better outcome than my husband and his kids. Congrat's on getting married.

OP, your first wife divorced you and turned into a grasping psychobitch... and you went and got remarried?

Failure to learn from experience, my friend, failure to learn.

Does she have borderline personality disorder?

For a friend of mine I think it was because her ex was no longer miserable like he was when they divorced.

She was no longer.... in control. He had someone else on his side. She didn't want him, she wanted him to be miserable as long as possible.

Maybe its about child support.

Some people don’t want their exes, yet do not want anyone else to have them either.

Or she could just be angry that you moved on quicker than she did & are now happy/content while she may feel this is unfair due to the way you may have treated her.

(Not saying you treated her wrong, just using the idea as an example.)

Us women can be a tad cray cray over this type of stuff.

OP, none of us know you, your new wife or your ex, all we know if your most-favorable-to-yourself account, so none of us can give you an answer about why your ex has reacted this way or whether she's being reasonable. Sure, people will respond projecting their own issues all over your situation and you can cherry pick the most favorable responses, but it's not like that actually helps your situation.

Why did you get upset when your ex remarried?

I've been divorced 7 years. She filed for the divorce. I Met someone a couple years ago and recently got remarried. My ex went bonkers. She has been saying really bad things about me to the kids and preventing me from spending time with them. She filed a law suit and served me papers days prior to the wedding wanting more child support and alleging all sort of things. The situation has gotten bad with the kids. They are not handling the stress very well.

1. If you asked for the divorce and then got it why get so upset when your partner moved on?
2. What did it take for you to move on yourself?
3. Have any of you done this to your ex husband and got taken to task in court?
