That's about the size of it. MN is now stuffed full of threads about: useless/drunkard/twattish manchild husbands (or abusive gits); crap in-laws with whom they are NC; OPs who either hate sex with their partners, or are pissed off because they don't get enough of it; people who are generally miserable in their relationships; people who live with nagging, demands, arguments about putting the bins out, etc, etc.
But these same people presumably once loved their DP/DH enough to live with them/marry them, shag them, and have children with them.
I'm not criticising anyone for that (am divorced myself).
But I do wonder why anyone bothers entering into a relationship, given that the end result seems to be unpleasant in one way or another.
Did you never love your partner, or did your loathing of your partner just turn from love into hatred?
