So not content with moaning about your own relationship you're now looking for problems in other people's.
You ask if things are normal a lot. Have you been stuck in a convent or something for ten years. Normal is as normal does, what one person finds normal, someone else might find pretty strange.
The point is your friend didn't seem that bothered so why are you? Chai is right, you keep looking for problems that aren't there.
Take a break, life's difficult enough as it is without manufacturing any more grief.
