Fwb Relationship 👩🏽👴🏻

I'm 18 years old & met this 43 year old on Craigslist for sex. I love have sex with him but he always wants to go raw which kinda makes me uncomfortable. Recently his wife found out and keeps threatening me. I was under the impression that they were going through a divorce. He said she's mental ill. Should I just ignore her or explain the situation to her?
