Depends who is breaking up from who.
What or who caused the problem?
Do you like her or she like you?
Hey in the end you picked her and she picked you.So that was your choice.
My chick(now wife) picked me, so that was a point in my favour.That was in 1971.I got married in 74,Still together now.So what is my secret?Ya got to give in sometimes(or at least pretend to)Also I never hound her and she never nags at me.If she does, well like I said, just say yeah,yeah OK and just leave it at that.I find that she soon forgets what she was complaining about.Now if you are arguing about sex well sometimes you just have to visit the Palmer sisters,they are on the left and right side of our body.Cause if you get married to a woman like that and then split up,you know it can be very costly and as far as getting laid,I'm pretty sure she will beat you at it.As for you you might get lucky(BIG MIGHT).
