Should I entertain this? It's currently contentious, with me accusing my cheating, lying stbx of abuse and seeking full custody. I'm sure she doesn't see it that way, of course.

I'm going after full custody. I have heaps of evidence documenting her destructive, horrible behavior including witnesses.

I don't see why I should bother?

I can afford a fight. We are both high earners.

I'll of course talk to my attorney but you guys have been through this and maybe have feedback.
