Is it normal normal to feel hurt when rejected by a friend?

So I met this woman on the train 9 years ago and we hit it off right away. After she moved away, my wife and I would go down to her house and have lunch with her and her husband. Well she invited herself to our house, but my wife doesn’t like to have people over, because she gets stressed out. So I told the lady we’d meet them somewhere, but she must’ve taken it as an insult because she didn’t answer now for almost a month, and I didn’t hear from her for Christmas or New Years either.
