Enforced vacation

So, unfortunately, I will be MIA for the next few weeks as I have a personal matter to attend to. No dates will be occurring, I will say that my First Boyfriend (FB) from high school is being super nice and calling me, but we have no interest in each other. My parents think we are going to get married because we have known each other since we were 15 and clearly if we are still communicating we must be in love. This is absolutely, 100% delusional. He has told me he'd rather die alone that marry me and I feel similarly. Otherwise, he would be the the perfect boyfriend/husband: handsome, super intelligent, good job, very kind, not a cheater, thinks I'm gorgeous. Why do I not like this guy?!
