Yes. Use your CS and math background to get a job in Operations Research. Use the OR techniques to do V&V on applications of AI/ML models.

Ie, Verification that the application/model do the job correctly and Validation that the app/mdl is appropriate for the business case.

This is not exciting but it pays well and people with the skill set are extremely needed.

I would recommend learning about the different "love languages" and understand that people experience love differently. In general try to provide a better experience for your partner by understanding their needs. Many people say that you can't be a good lover of you don't practice "self love" first, I agree with this. Along those lines, if someone consistently treats you poorly and you've tried to communicate that you don't like it, remove them from your life, your happiness comes first.
