MIL,FIL and SIS and BIL moving in with us!?

recently was told they have to pay the months they missed starting JuNe 15, were **** 16 already!( So they can stay) So now, I have a feeling they would all move w/ us! My house has 3bed and 2 of dem is vacant! but my mom will move in a few months, and hubby n I have agreed yrs ago about this! And this issue with my MIL happen, we didnt know she stop paying her damn house. And just recently she ask money from us, we had to take out a loan so they would stop calling us! And yes were paying for that stupid loan and interest coz they cant ******* manage their own money! She works on call but still! Whenever they get money from her unemployment and paycheck theygamble it all and leave with nothing! She has other kids, yet non of them offered help when she was asking for money, yet all of them have money except us! We even gave them 500$ when we got our tax,our tax is gone we paid our own debt so we wont have problems when I go on my maternity leave. We have one car right now, I work grave he works swing so perfect! but if they move with us, his dad goes to doctor M,W,F he cant miss it! his mom works on call. So how the hell are gonna make it with 1 car and 4 ******* peeps have to use it!

i dont want them in my house thats for sure!

So now tell me if im being selfish! I just cant hav that many people in my house! ill go crazy if ever!

My SIL dont hve a job and her husband is a retired army theyre not from here, but idk until when are they planning to stay here in reno.
