Same here. I got divorced in '91 . . . still got cold feet. It is gonna take an exceptional woman for me to do that again.
My first husband, like you both, has never remarried. I dumped him for cheating. I've got this funny thing about monogamy that just went batshat crazy when AIDS hit the country.
Not everyone is 'fit' for marriage. It never works when one person is all 'take' and no 'give.' Usually that person never realizes how selfish s/he is.
