Oh god, my ex's (we had been together about 3 years) parents wanted her to date their friend's son. She didn't. So every day after church they'd go out some place and have them drop their son off with them and forced them to go on dates and have him pour gifts onto her and sob on about how horrible his life is with Hepatitis (he lied that he was dying from it and later admitted that he was an inactive carrier of it and isn't affected at all) until she dumped me. My parent's advice? I should have just been more of a bachelor and not put up with being with girls long-term because they'll never make me happy, as in fuck them and don't date them. That came from my mother, about a girl I had been with for 3 years, who had been the person who helped me cope with and overcome my chronic depression and actually made me a happy person -.-
Oh, and the reason her parents gave for trying to get her with him? Because I always have sex on my mind and am a horrible person, and he's a good kid. He would spend every day in church trying to get into her pants (she would complain about it to me like every week), and the first thing they did when she left me for him was to buy her birth control and condems because they knew all they'd be doing every time they saw eachother was fucking. Honestly, what goes through parent's minds is fucking beyond me.
EDIT: The people saying that you should never listen to a person who's cheated kinda bug me. I mean, not everyone is being rediculous, but there seems to be an assumption that if something happened with someone else, they're a sleezy bastard who spends all their free time screwing other girls. I guess it's a fair assumption to make in most cases, but as someone who's had someone try to force themselves on me and then got accused of cheating for it, it just bugs me to see that >.<
