In law problem HELP

Okay so my in laws have moved in a year ago because they stop paying for their home, they were suppose to save up
For 3 years before they moved in.. They moved in with no penny to their name. My husband and I have been providing for them for a year now. The FIL broke his foot and needed immediate surgery so we had to pay 5 grand on our credit card and they said they would pay us back. They don't pay rent when they said they would give us 1000 a month And they are hoarders and I mean HOARDERS like that show and go to the casino all the time. They have put an extra 3 grand on our credit card to pay for things they couldn't afford. Not to mention that we have had to dip into our savings and used 8 grand to pay the bills because they are constantly racking up the bills and wanting a Lucent life that we have to pay for since the bills are in our name. They are extremely filithy and I have to constantly clean up after them n they just dirty it more right after, I refuse to clean up now and I have to fight for the kitchen to cook for my husband and sometimes the FIL tells me he is cooking and doesn't!! The mother sits on the computer all day and doesn't cook or clean and she has brought 4 dogs into our home and let's them roam free and also ruined our furniture and carpet and now we have to dip into our savings to repair this. The MIL has a job now and the FIL. Has relieved a raise. They still don't pay us even when we asked again. They constantly get into my husband and I  arguments, or cause us to argue. they try and tell us what to do or want to no where we r going and all this stuff.  I Am 3 months pregnant and they try and tell me what to do with my pregnancy and how to care for my baby and the MIL keeps telling me it's her baby and makes remarks to me about the baby. They have destroyed my home and it looks like a pig lives here. I told my husband no credit card for them and we also told them we wanted to move and by a new home n they can keep this home and we will switch the mortgage and title in their name which is awfully generous and they told us we cannot move out and no. They tell us how to run our home and how we can't do certain things in or home bc of the dogs and by the way the dogs are not good with babies or kids and I just want them out! I don't want a strain on our marriage and I understand it is an emotionally burden for my husband because he has to say it and doesn't want to hurt them but he is fed up too ?? I think that 3 months is enough time to get out, they need to stop going to the casino and leave! Any advice on this or how to ask them. It's driving me into depression.
