Third party removal spells?

Hello everyone! So I wrote in here a few days ago about my relationship situation and I was wondering if anyone had recommendations on third party removal spells? I know cord cutting is an option or the lemon spell. I just want to find a good option because right now the third party is pretty obsessed with my SP and they are on the the phone and interacting 24/7. I also just don’t want to do anything malicious or that could possibly harm me and my SP relationship.
