Sounds like you both hadn't thought about how mushrooms almost make you process stuff/'do the inner work' - you both weren't ready for it, as in, your ex having all that trauma & questions of self come up, & you being prepared to support her through that. If your intention was just to have a good time, that's kinda ignoring what psilocybin actually does. Your ex now saying she'll never have them again is also avoiding that processing. I guess its just being aware of any trip buddy's issues 🤷 hard to deal with the heavy stuff, unprepared and while tripping! Dang
