To answer your question. No this isn’t a healthy friendship and it has no potential to be one. Just my opinion. But certainly you can be roommates. Or occasionally keep in touch.

Personally I’d not indulge in unhealthy relationships out of boredom. I don’t understand boredom. There isn’t enough time in the day, no time for being bored. And life is too short for unhealthy entanglements or being bored. Just my take on it

Saying that, there is no problem with becoming roommates unless of course it will mean moping sessions will become daily hahaha not weekly. Oh boy. Train wreck is understatement.
