Maybe I am lucky or maybe I did more homework than most (after some bad experiences with other filipinas and money - lessons learned the hard way) but in nearly three years my in-laws have never once asked me for money or for anything, and my wife has never asked me to give them money. I set some up front ground rules when I met my to-be wife but it turns out they were not necessary. My in-laws are from the mountains, lived off the land, traded crops for rice and other food, and raised six kids with no income other than what they produced on a small farm. Dirt poor but proud, and I think it is that pride and the type of people they are and the simple lifestyle they lead that eliminates asking me for help. It turns out they don't have to ask because I give them money for certain things because I like them and respect them and I choose to. They don't live with us but now they live close to us and we like that. I can tell you being my wife is young it is nice for her to have her mom to talk to and to help her with the baby. The boy just loves his grandma and she watches him sometimes if we go places with no problems.
Maybe mountain folks are less greedy than some city folks or like I said I am one of the lucky ones.
So not every relationship here is a horror stories with in-laws.
