Brothers! I Could use some help as I'm scared out of my mind.

Backstory: I dated a women for a few years and she decided to start seeing someone else behind my back. Long story short, after the breakup she filed a restraining order against me based on a false allegation of assault (unfounded). Unfortunately I represented myself (huge mistake) and the judge granted her the RO. Thats the basic backstory. I have not seen or spoken to her since.

Her new boyfriend dumped her and she is now threatening me with a lawsuit for money she spent on me/us during our relationship. She made a considerable amount more than me and paid for nearly everything we did together (lavish vacations, bills, etc.) She is now claiming all the money she spent on me was a loan. I never agreed to borrow any money from her. I never signed a contract. The money was not a loan at all. What options do I have to fight this?

For the record, she never lived with me.

Note: YES! I have hired a lawyer. I just wanted to brainstorm here before meeting with my attorney.

Thank you for you time!

Edit: I should clarify that her attorney sent me the letter.

Also, I spoke with my attorney today and he said it’s probably a bluff. We shall see. I’ll keep everyone updated. Thanks for the support! I’ll continue to respond to anyone who comments.
