MSRMinis - I'm kinda glad you spoke up on this..
I'm REALLY strongly opinionated on this.. I have had ONE terrific stepfather and a whole boat load of crappy stepmoms. But my opinion stays the same.. If you marry a man or woman who has children its not your place to say whether its right or wrong to ask for assistance.
I'm 21, I've been trying to make it big on my own for years now. I've been handed a whole heep of crap for a life and yeah. I occasionally have to call my mom for help. My stepdad would NEVER ever step between my mom helping for whatever reason. But then most of the time he steps in as her HUSBAND and MY STEPDAD and takes part as a parent helping a child. Everyone's opinion is different. I should be making it on my own right now but hey I'm not.
You know my stepfather single handedly burried my son for me expense wise I couldn't? He never batted an eye to it and if I ever have another son he'll be named Joseph out of sheer respect for a man who remembered to care when most stepparents are extremely rebelious and tend to demolish families..
A torn family with stepparents is a healing family in my eyes.. Stepparents are bandaides.. they can do great wonders or hurt like heck.
So I guess the question is are you paying for everything or is the hubby? Are you not interested in teaching the grandson how to drive and sharing an awesome hobby? Are they saying YOU have to keep the steer? Would it be the same if they were Really your kids? Not trying to be rude, I'm just really curious..
