Treated this girl right even though I didn't see a future with her, bought her a 300$ gold necklace for her birthday.

We broke up a couple days ago after our first therapy session which she was not contributing to at all. We were in therapy to try work through problems she created.

We had agreed I can see other people but she kept going through my phone while I was asleep and confronting me, and continually lied about changing but never put it into action, so I dumped her, I had already checked out emotionally as well so the crying, bargaining, etc. Didn't work this time.

She called me asking to talk and saying she wants to give me my birthday present (my birthday is December) and even though I deserve it I told her to return it cause I don't want to give her hope and I don't want any more memories with her.

Now I'm pissed she has that token around her neck from me, and I want to tell her to pay me back for it or give it back. I spent thousands on dates etc. Throughout our time together anyway. I don't feel like she deserves this.

Should I tell her to give it back?
