Yes we should stand on our own two feet as adults, but that doesn't mean accepting help makes you weak or spoilt or whatever.
I've always been 100% reliant on myself to see me through any sticky spots, my parents have money but have never gifted me any. DP is somewhat the same although her parents have given her quite a lot she's more than capable of managing herself (or, with me, rather).
It's very strange belonging to a family where giving is the norm as opposed to my family who on the occasions have lent me money, have had a time frame they want it paid back in.
DPs parents paid DP's college fees as HECS wasn't available for them, and have just told us there's no need to pay it back, which we are very grateful for. When SIL left her ex, she and nephew moved back with the ILs and they bought her an almost brand new $17k car and there's no sign of her moving out any time soon. They're also taking her and nephew on a trip to visit family overseas.
That's just what they do... while DPs mat. grandparents are very well off, my ILs have made their money here, they have their own business and 7 properties in Sydney and Melbourne, including their own.
I know they're there if we do ever fall on hard times, but we are doing fine on our own.
They're not throwing money left, right and centre though - when DP lived at home, they charged her $200 rent and that became the money she lived off while studying.
*shrugs* everyone is different. We've never asked to borrow money, but it's nice knowing we have that support if we *do* need it, which I truly hope we won't. They offered to help with paying for fertility clinic fees etc but we don't need to go through a FC anymore and even if we did, I wouldn't want them to pay for it anyway.
