Thanks everyone for your answers
In fact, I do try holding back and seeing how the other person is feeling, and keeping a distance if needed, but it looks like it's not enough. Although, thinking about it, I realize that it cannot be the case with some people, I guess it does happen a lot, and I'll try to save at least what might be due to this fact in the future.
In the meantime, I just hope that he'll eventually calm down and miss me... it's happened in the past, so why not now?
(cannot stop hoping, sorry...
)
Great support group, thanx a lot everyone!
