Job on the side

I (39) work as a private investigator but need to work another job to get by. As being a PI doesn't pay enough regularly enough to get by on. There are some weeks I really busy and others it really dead. My other job allows me to do online searches and so doesn't impede my PI work. Most of my work is just checking people are who they say they are, rarely I get jobs checking on a wife or a husband being unfaithful. But in 2018 I got a job checking on the wife of a premiant local businessperson 57. He thought his 34-year-old wife was playing up on him. She wasn't, but he was on her and that's why he wanted to find something on her so they could get divorced as they had a prenuptial agreement in place. Anyway, he wasn't satisfied with my report and refused to pay me for my work. So, I told his wife of my investigation and all what I had found out. Her lawyers were very happy with what I had found out. Especially the pictures and video I provided; he had made one big mistake he didn't pay me. But his wife did, and we became close after her divorce, and she got pregnant to me. We don't live together, but regularly see each other and still having regular sex and have a gorgeous daughter. Her ex married his mistress and is again divorcing as she liked to spread her affections around as they say. Got caught by another husband's wife with the husband, pity my former employer forgot to have another prenup with his new wife, he really could've used it this time.
