This is probably the opposite of what you're looking for, but semi-regular, um, psychedelic therapy kept me in a relationship that third parties call "abusive."

This is probably the opposite of what you're looking for, but semi-regular, um, psychedelic therapy kept me in a relationship that third parties call "abusive." During the experiences we were in absolute perfect unity, learned lots about each other, and defaulted to kindness. This carried over for a few weeks where the experience would be fresh in memory. I fell into the trap of "it is possible for her to be better, so she will get better because she loves me."
