As I think I've said here before, he and I get along well when not living together...truly...we always have been that way. Maybe we were just meant to be that way!
Life gives us clues about what will make us happy, mentally. Sometimes they're as obvious as the nose on our faces, but we ignore them.
This is a big, big sign. It is perfectly fine to care about someone from a safe distance....it can be the makings for a very nice life. We're tempted to 'do what everyone else does' and try to fit a round relationship into a square hole sometimes, but when something is as obvious as this (above) I would certainly pay attention and respect what the universe is trying to tell you.
