Dear Diana,
I have a boyfriend who I am serious about. We are off to different universities in the US in September. Having had no experience of a long-distance relationship before, I am worried that our relationship will fall apart. I’ve read many worrying things about couples who go from regular relationships to long-distance relationships. Am I worrying too much because he does not seem to show any reaction? We are both 19.
