I've been seeing this guy for a couple of months now. We first started talking and went on a great first date. We have been out on several dates after this, made dinner for each other and have spent a lot of our time together. He got sick this past week and has completely fallen off the face of the earth. I'm probably overreacting and he just needs his space. I've avoided talking to him since he started ignoring me, but today I messaged him asking if he was feeling any better and to just let me know that he is alive. Should I expect an answer or what?
