invading my house! (LONG)

sorry this is so long, skip to after the second gif for most recent events. okay so a little back story, i lived with my in laws for about 4 months (paid $200-$300 a month) 2 years ago and we've had our own place for a few years now ( i say our own place, but we've always had roommates until about April of this year). they got evicted fron their house the first of July and asked if they could stay in my "extra bedroom", which is supposed to be my daughter's nursery, for 2 weeks while they found a place to stay. i told them no, my fiance told them yes without talking to me. well july 1st rolls around and he informs me that they are going to need help moving into my nursery! so they move themselves and their 2 cats and 1 GIANT misbehaved dog into my house without my consent. i dont have doors in my house other than the bathroom because it's unfinished so 1st problem is that i have no privacy at 9 months pregnant. i was due July 14th which is when they were supposed to be out by. july 9th comes, and baby decides thats the day. so now I've got a baby and no nursery and no privacy. July 14th comes and goes, and they make no effort to leave or find somewhere else to stay. by this point I'm already upset

and tell my fiance that they need to go. he tells them to either give us some money for rent or to leave, they say that they are "broke and cant afford to pay rent or find anywhere else".

i know that this is bullshit because they eat out every night and buy hundreds of dollars worth of marijuana every week and FIL akes about twice as much as my fiance so there is no reason for them to not have money.

now it is the end of august and not only are they still in my house, they have not paid a single dime, and today i came home from my 6 week pp appointment to a house FULL of people. they informed me upon walking in that their son and daughter (who are 20 and 24!) will be living with us for an undetermined amount of time. they didn't ask me, didn't ask my fiance and still haven't paid rent. i literally have people sleeping on my front room floor and now 4 extra pets in my home with a 6 week old baby. i asked my fiance how long this was going to be and his reply was "as long as they want" because his brother just got out of the hospital so apparently that means that they can just walk all over me and have no concern for what i want and need.

not only that, but with 4 extra people you would think somebody could help me with laundry or dishes but no, I'm the only person who can figure out how to clean without making an excuse not to do it. i feel like a freaking slave.

they are totally violating my privacy. they will just walk into my room and take my daughter from me without asking or anything. i woke up to my daughter not being on my bed where she sleeps this morning and MIL had her in their room while they were smoking pot when ive told her multiple times i dont want her around it or for them to even do it in the house but they dont listen. 😭
