Prenuptial Agreement - postnup after infidelity

I've been trying to resolve this on my own but I'm stuck.

postnup after infidelity. I've been dealing with this for about 13 weeks now and the situation isn't improving.

I have already tried to resolve this directly but the other party is not cooperating.

What are my legal options here? Is it worth pursuing?

Been there. Here's what I learned.

I ended up escalating to a supervisor/manager, which cost about $1-3 but saved me a lot more in the long run.

I've dealt with this before.

The thing that gets people is filing with the appropriate government agency. I'd recommend gathering evidence first instead.
