Been shot at but never hit so I can't relate other then to repeat what you already know... they don't know you and are not looking to finish anything.
As far as your wife leaving... That won't happen because of you getting shot and her having to do a little extra here or there.
Women don't think like guys in many areas. You have a wonderful wife and she will stay by your side.
Just be sure you tell her you know how blessed you are to have such a wife.
