Frustrating situation

Two weeks ago me and a friend ended a friendship and it was messy. In short I was jealous of her spending more time with her boyfriend and she ended things. A few days later I asked a mutual friend to check on her to see how they were doing. My exact words were "I'm asking you to spy on them only to see how they're doing". The friend told her and this triggered a panic attack due to past relationships. Days later she sat across from me at lunch and accused me of staring at her, saying that she knows where I walk everyday and I changed it. After that we talked things out and moved on. However, another few days later I decided to leave a quote for her to let her know that everything was fine. I hindsight, I should of left well enough alone and she got mad, reasonably so. And just recently her boyfriend accused me of stalking her (which I didn't) and after I said I want nothing to do with her because she's toxic and rude, he kept saying things like "just making sure we both get it" or "great than stay away from them" after I made it clear I want nothing to do with them. Then his friend joined in and said "we all insult each other here but when we get to you, you thrash about and throw hate ' after they accused me.
