cursed

so for context, my ex is insane. like actually crazy. she used me for years, then after i found this out and broke up with her she sided with people that were sending me d3ath thr3ats, claimed i was cheating on her, d3adnamed me, became incredibly transphobic and so much more. she convinced my best friend's grandma that we "shunned her because she wasn't nonbinary anymore", which is completely untrue and incredibly ridiculous. now, she has been and still is a witch. since i broke up with her i have always had the thought, what if she put a curse on me? i developed terrible commitment issues that ruined all my relationships after her, and the rest of my life has slowly been crumbling as well. i don't want this one to follow, i want to feel some happiness again. am i crazy, or is there a chance i really am cursed?

(for more context, i am pagan, born and raised, and fully believe in this stuff).
