I (45m) had to get insurance for my wife (38f) through my work. We were to pay 50/50. She hasn’t paid me and I asked. What can I do ? I don’t want to ask again.

I pay 80%of the rent and everything else pretty much . Her employer does not give insurance so she got it though my work which come about $650 per month. They have been taking the money out of my check. She sent me the part of the rent and I asked about the insurance .and She was in The middle of something and did not send it that was that. I am not asking again. She was supposed to look for a job with insurance for the last 2 months and hasn’t done so. I don’t want to start resenting her but I really don’t thing is fair.
