I know of two women who after 20+ years of marriage had their husbands come out of the closet and leave their families for a man.
One woman was my third grade teacher-for awhile I wondered if I could be fooled and marry someone like her husband, a nice guy who was very involved in their church. It must have affected me as a I married the manliest man I ever met. It’s a trade-off, thoughtfulness and sensitivity are not his strengths ;).

There is no definitive test for who someone is sexually attracted to, so anyone is vulnerable to be fooled in that sense.
