Third party remotal spell

Hey everyone, I'm in a long distance relationship and will reunite in about a year from now with my boyfriend, we have been together for 7 months now, and one thing that keeps coming up is his toxic ex [she is actually toxic and its not just him saying that about her, that girl is mental- as in lying about injuries and almost faking her death and only informing his mom so she worries about her and guilts him to get back type of mental] its taking a huge toll on him specially, and on our mental health.

SHE JUST WON'T LEAVE US THE FUCK ALONE!!! her and I live in the same country just different cities, and I thought about going to her house so many times to confront her but whenever I do divination I get told to sit my ass down.

My last resort is a 3rd party removal spell to keep her out of our lives. I'm not too familiar to banful spell work to be honest, my work is mostly manifestations and protection cleansing etc.

What type of 3rd party removal spell do you recommend? Something that you've tried and it worked. I need this woman out of our lives for once and for all. I don't wish her harm, I just want her out of my hair. We're not kids, we're in our mid 20s with jobs
