Husband still ask for other female numbers

My husband are newly weds and not to long ago I saw that he asked for a woman number at a restaurant he didn’t know that I saw what he have done because I stayed in the car while he went to get some food.. but I seen him chase her down just to make sure he had the right number… I was sick to my stomach saying that we just got married.. it’s been a week now since it has happened I didn’t question him about the matter because I don’t know if it’s as serious to even mention to my husband.. idk I just want some advice from the seasoned married couples.
