In today’s legal environment, a wariness of marriage is only sane risk management.
P. S., I’m long term happily married, myself. But, I know many who tried but didn’t manage that.
Especially for males. I’m in the same situation as you, but have seen here and in other forums what decades of radical feminism have done to the family court system, and what that does to divorced males, who are treated extremely poorly by that system.
