Can you see if you can prove that maybe they scammed you into renting with them? Maybe they already knew they were getting foreclosure and just wanted to trick you with a good deal into getting in there? Maybe you can talk to a lawyer.
I agree that you should talk with your fiance because he could help sooth you do you won't feel alone and feel that burden of holding things in. Also if you pray... pray and believe the Lord will make a way
Sorry things are so stressful. Hopefully you aren't still paying rent since home is in foreclosure and u can save that money. Does he have any family that can help? Talk w ur fiance about concerns and come up w a plan together. You shouldn't be holding ur worries in to protect him. Good luck
Jus try not to stress and remember there are options you jus have to find them. Also dhs may have info on rentals. Or help
Look for rentals...sometimes places arnt always listed bc home owners rent out ask around. Also you may look into buying foreclosed place. If you had a contract you should be protected. Goodluck but try not to stress something will work out. Charities and churches may have info or be able to help.
