Congrats!
I hit 28 years this year.
I remember at my bachelor party my one friend, who was married, said to me, "It's not always 50-50. Sometimes it's 80-20."
Somehow--although I'm sure I was quite drunk, and I know he was, this made a lot of sense to me.
Sometimes you have to give more than you want to--sometimes a lot more--and vice-versa. Maybe overall it settles out to a 50-50 split, I don't know. But be willing to compromise.
By the way--he was married for about two or three years before the divorce.
I'm still married.
Go figure.
