The Scorpio Man - Is this a normal behavior?

I have had an email/phone relationship with a Scorpio man for the last 4-5 years. It has been completely platonic, with no real expectations of a relationship because of our locations in the US. Recently, I had the opportunity to meet him in person, which was a completely random act - and we both hit if off incredibly well. I know that it is the Scorpio nature to 'say what he means'. He was completely taken by me and I with him, and by the end of our trip he was asking when I would be back to visit him since his profession minimizes the opportunity for travel. I told him I would come see him in a couple of weeks, and he was agreeable to that. He also mentioned that I was 'it' for him and I agreed that the feeling was mutual. When I left all was good and I heard from him like I knew I should, and within a couple of days he fell sick. I understand what he is going through because lol I think I gave him the flu I was just getting over :) anyway, it's been like a week, and while I know that Scorpios don't show weakness, could this be the reason that I barely hear from him now? Does he see him being sick as a sign of weakness, and is holding off on talking with me until he is 100%? I plan to go out to see him in like 10 days, and he won't even give me a response on if the trip we planned is going to work on his schedule. He will text me at least once a day with no real answers, just telling me how miserable he is (poor baby) and once with he misses me too (in response to my text). I would hate to go see him and he not even be available? Should I give it a couple of more days, or should I just wait to hear from him?
