Few shidduchim that I know of went through smoothly without a hitch. Most have some sort of roadblock somewhere. It could be an unwillingness to go out, no emotional connection, parents issue, something he/she said, the list goes on and on. The point is, have a Rav and/or a professional shadchan that knows you to guide you.
I also agree with Middle Path. (You see, MP, you should stick around!!)
