Thread: Renting from inlaw and she is moving back, should I be obligated?

Hi all,
I am from PA and new to the board...My fiance (C) and I have been together for 3 years 4 months and we've gone thru alot... this is the course of events in numerical order to make it more understandable...

1. C's mom meets guy online, moves to Arkansas to be with him
2. C's sister, her boyfriend, her 11 year old son move to AR to be closer to C's mother- C and I rent his sister's house when she moves to AR, we pay mortgage and ALL maintenance bills...
3. C and I have problems and he feels to fix them, our only option is to move to AR also...
4. I say no and we don't move...
5. We visit AR and C's mom gets married to the guy she met online
6. C's sister is prego and has baby...
7. C's sister and fam has issues w/ the mom's new husband
8. C's sister wants to move back to PA (they've only been gone 8 months)
9. C's sister, her boyfriend, her son and the new baby move back to PA 2 days ago...
10. They have no jobs lined up, they are staying w/the boyfriends mom until C and I can find some place else to live, then they will move back into the house...
11. C's sister is being kind in giving us plenty of time to find something and move...said to take our time...
12. C's sister asked that we basically KEEP her son at our house so he can go back to his old school and stay in the same district...So...we have to basically raise him, help him w/ school work, get him up, on the bus, off the bus...and pretty much wait until SHE is ready to come pick him up on the weekends. This boy who is 11 and too big for his britches, treats me like I'm his sister...he does not look to me as authority and has treated his own mom like this forever. He is horrible in school and needs a good *** kickin'.
13... I would not mind, however, but the boys mom does not put any effort into raising him herself and I feel is unloading him on us now that she is back in PA...her mom is not here now to keep the kids...she is still back in AR. SO, there's a baby now too...and I was told that the baby will probably be with us most of the time too...my fiance doesn't seem to think it's much of an issue...(of course it isn't cus it's HIS fam!)...we clash on how our families act...he says mine are too introverted, where as his family likes hanging out and doing things together, and doing THINGS for each other...He says my fam members only get together on holidays and that even then, we are being "fake", that we are only pretending to get along...we WANT to get along but we all have our own lives to upkeep. We take care of ourselves and do things on our own before we ask for help from one another...my fiance was living w/ his mom, and sister when I met him. They have always catered to one another and I think it's only cus they need the financial support not the loving support...sure they love each other very much and would bend over backwards to help each other out but they take advantage of each other and the love it TOO BLIND to see it. His sister has never stood on her own 2 feet w/o her mom and same goes for my fiance. They are all very lazy and if they don't like their jobs, they just quit on a dime and file unemployment. As long as they have someone to fall back on, they don't give a rats ***. SO...now that my fiance's sis is back with her boyfriend, son, and new baby, she is looking to unload her kids of on us...I hate it. SHOULD I BE OBLIGATED TO HOUSE HER SON JUST BECAUSE WE ARE RENTING HER HOME? SHE WILL BE LIVING ONLY 30 MINUTES FROM HIS SCHOOL...AND WON'T BE WORKING! SEEMS TO ME SHE IS YET AGAIN, JUST GETTING HIM OUT OF HER HAIR! KEEP IN MIND THAT I AM ONLY 24 AND HAVE A 7 YEAR OLD DAUGHTER THAT I HAVE RAISED ALONE AND SHE IS 2ND IN RANK IN HER CLASS...EVERY OTHER WEEKEND SHE GOES WITH HER DADS FAM AND THAT IS MY "FREE TIME"...BUT I CHOOSE TO WORK A SECOND JOB WHEN SHE IS THERE FRI AND SAT NIGHTS SO I CAN MAKE EXTRA $. AND HERE IS MY FIANCE'S SIS, NO JOB, AND BOMBARDING ME WITH HER KIDS...HOW WOULD YOU ALL REACT TO THIS? I AM THE ONLY ONE ALSO, WHO IS MAKING AN EFFORT TO FIND SOME PLACE ELSE TO LIVE...I WANT TO GET OUT ASAP SO SHE CAN MOVE BACK INTO HER FREAKIN' HOUSE! ONLY SO I WON'T HAVE TO PUT UP WITH HER SON AND THE BABY!
