Is love real?

[Ahriman]

It's common in many mental health disorders. Consider it a type of self preservation. He enjoys the fantasy more than most of the negative consequences. Once he encounters a consequence that causes enough harm then he'll attempt correction. But it typically only lasts until he feels no longer in danger of further harm.

It must be some sort of sadistic obsession.  Keeps posting and baiting as if he has something meaningful to discuss, but as you said gets scared and runs off.

If you could explain this in further detail, I might consider going to therapy. I would want something to actually discuss with the therapist, not just random bullshit. And no, discussing my online posting habits doesn't count.
