Minor details slightly changed because I am in litigation.

I was married for 5 years, separated the past year and a half. Ex wife is asking for lifetime spousal support and for the court to have me take out life insurance on myself for her. I’m already giving her 50% of my income by court order, she wants that amount increased and I don’t know how I’ll be able to survive if this continues. I can’t live off of 2k per month for all my expenses in my area. no attempt to settle on her part. She is dead set on taking this to trial. she also makes more per hour than I do, has lied on the record about how much she is working (along with many other things). One minor child who she is seeking to make me an every other weekend dad of despite the forensic evaluator saying I am a fit and loving parent and my time should increase, not decrease.

Does anyone else have experience with this sort of thing? How did it turn out? Any tips for trial?
