I was friends with a lady for about 2 years. During which time I had gotten pregnant. Money was tight so she gave me things from when her daughter was little. A high-chair, swing and various other small items. I had mentioned that if she needed the stuff back (she was hoping to get pregnant even though she was not married and not in a good relationship) I would give it back when I was finished with it. She told me that was nice but it was not necessary. She said she was happy to give them to someone that could use them. Shortly afterward she lost her job and gotten messed up in selling her prescription drugs. I decided I did not want such a person in my family's life and proceeded to slowly cut ties, trying to be nice about it. She, in turn went to CYS and my daughter's biological father and told them horrifying claims of mistreatment toward my daughter. Neither party was able to prove any of her claims and all cases ended in my favor. However, she then tried to mend the friendship. I told her to leave me and my family alone. She refused so I had to involve the police. They warned her of pending harassment charges. She seemed to take heed and I have since moved and gotten married. Now, after over 2 months of thinking I was rid of her, I received a notarized letter stating that certain items were lent to me and she is requesting them back or their listing price. She states that she wants to meet somewhere to collect them. I think this is just a ploy to establish contact. Cause she had straightout borrowed a workout program from me and I had just decided to forget about it because I wanted rid of her that badly. I'm not sure what I should do.

Send her a notorized letter that she had stated xx amount of times they were gifts and keep a copy for yourself.
It will be her word against yours if she bothers taking you to court. The Judge should see the pattern and realize she 'changed her mind' about it being gifts due to spite.
She probably has no receipts and she has no signed agreement from you so I doubt she would win any full amount she went after
Its your word against hers and with her track record you sound more reliable.
The Judge might find some items in her favor but would grant used prices rather than new prices.
I think it will turn out in your favor.

Don't be friends again cause you'll only repeat history--her pulling her stunts again

If you no longer need the borrowed things I'd give them back pronto so she has no reason EVER to contact you again. Either take them to where she lives and drop them off or have someone else do this. This way she cannot come after you in court (even though you may win) and you don't have the future headache to look forward to.

If you truly want rid of her this is your best option.
