It is understandable you struggle figuring out what’s good relationship if you never had one. How was your parents’ marriage? Sometimes it stems from how we grow up.

If you are happy with this guy then it’s all good, but if not then you got your answers

I think it’s safe to say that relationship is emotionally unhealthy if you have to question why he does things.

I second others that finding out “why” is not only unimportant but also impossible. If your boyfriend even tells you why, you have no ways to know what’s the reason as he might not be truthful .

I still find it weird that after living with you for years and wanting to marry you, he leaves to a different country and it’s unclear when he’s coming back. When did you see him last time?

I didn’t mean to be dismissive, My apologies. I was trying to understand what’s with the 3 week relationship. I didn’t realize it was at a very young age. I see now. At a young age everything seems a big deal
