i have currently signed a land contract for a home. ?

I am now having problems with the girl i bought the home from. The home was going into forclosure, I went to the bank and they said i could do a contract on the house.

the girls still thinks the home belongs to her. She doesnt hold the contract, the bank does( i am paying the balance of what she owes)

I have been told by countless others that it isnt her house anymore. I am scared and confused.. i have had a protection order on her but it doesnt seem to have done any good.

can someone just please tell me if the house is still hers and does she have a right to come over and inspect it whenever she wants and have the extra key? Any advice would be greatly appreciated.
