Hi medicalfox. I didn't realize where you lived w/ your bf was unclean in this way. I think a studio is a super suggestion! If you have no or a poor credit history, you might need a co-signer. Someone with a good credit history who would sign the lease with you. (They would NOT live there, just be financially liable if you didn't pay) this is very common, and the leasing office could tell you all about it. Often the co-signer is a family member, but it wouldn't have to be, it could be any adult who willattest they have known you the required number of years.
I would absolutely, under NO circumstances return to a home in which I was being hit. Please don't. Its your decision, but it makes my heart ache to think of you living in that kind of fear or numbness and danger.
Small apartments are often very affordable, and give you a safe environment where you can control the cleanliness, who comes and goes, when you come and go, etc. I think this could be ideal!
Good luck!!!
