"beating a dead horse"
"waiting til the cows to come home"
[Insert other archaic agricultural references to waiting and waiting...and waiting....]
Do you wait too long for a man to improve, to act as you'd wish, to fall in love, to behave more affectionately?
I read something last week that basically said, "If it isn't fun now, if you are suffering in the relationship now, but are planning on being happy "someday" (when he leaves her, when their kid goes to college, when he stops his addiction, when he realizes how much he loves you and stops cheating, whatever) this is a loud clear blaring warning signal that it's time to GET OUT...now."
What do you think?
