3 months into divorce process, we "amicably" discussed our split. This was her decision to leave abruptly. She agreed, multiple times to provide the ring and I have it in writing.

Granted I understand she has fully capability to keep it as its a gift, though she used this ring as leverage to get everything she wanted. She got 50% of security deposit (though there was damage and will cost more), her stocks which we shared, her tax return filed & didn't even pay the next month of rent when she should have given at least 30 days notice (divorced me on March 26th). Contract legally states 30 days prior.

I overlooked most this and agreed when she insisted she would provide the ring pending completion of all these tasks.

Now its complete, I have the final 1k for her tax return in my account. She now says she does not intend to provide the ring at the last step, but wants her tax return back (we filed jointly for fiscal year 2021).

I indicated I will gladly provide when you hold up your end of the deal. Back and forth and she once again blamed my family for reason for divorce, pain and suffering she went through (was tough times, my mom had mental illness and father brief alcoholic, but much better now.) This hurts kind of deep because it was about 2 years ago when things were shit there. They have significantly improved but she has not healed from that apparently + this situation was completely out of my control.

Now, she basically used me to get what she wanted, and isn't following through with the initial agreement. I directly asked her if she intends to give it back, and she made that a very direct YES once things are completed. I was totally fine either way, as it was a gift.

I am only bothered how now she just changes course. It would have been one thing if she DIRECTLY stated NO, I would have respected that much more. But now, I feel played and disrespected, lied to and used. I still have her tax return, but considering I didn't charge her for April rent when she was obligated (~1.5k), and she flat out lied to me, I don't really want to give her the money until she holds her end of the deal.

I am trying to be very reasonable and fair but I am struggling with this one to know my next move. I am so close to giving her this 1k and say good riddance keep the ring. The money is only a small blip in time, but I am still so fucking bothered by the blatant lie and use of me to get what she wants with no remorse. She left me on my fucking birthday.
