Well I don't know about the adultery laws but from what I've learned - few exist any more. And most people do not get spousal support if they have a job.
I did not commit adultery. I did not know my husband was having an affair. He left me, moved in with maggot and never looked back. Do I get spousal support? No. Do I share in his pension? No. Do I get help with tuition? Once in a while when he feels like it. Child support? Only the minimum court ordered amount which was $321 month until D turned 18. Have not had a dime from him in months.
I still think I got the better part of the deal. I'd be going to court for sure if I were you.
