Don't start questionning yourself. Just do what comes naturally. I know you are not as old as I am but one thing I never put up with is games. So here is my take on your guy friend....what usually happens in the world of cyber dating is you have serial chatters or daters etc. What I mean by that is it is very easy to meet with someone and then come home and back on to the computer for more chatting and pursuing (semi anonimously). You follow what I am saying. So in conclusion, never been married, does not come on to you when you invite him over, goes dark.....add it all up and it does not smell nice. Keep sampling the buffet BBJ and don't be apologetic for being who you are....
