Should I stop overthinking?

I am talking with a guy from England, we live far away from each other. We have talked for many months and we have also talked about meeting. He has mentioned a girl best friend before (that he very rarely meets) and I am totally ok with that of course. Two weekends a row he hung out with her, at a market or so. I am secure in myself but I am just scared of beeing naive. In my experience all the guy friends I have had have wanted something more than just friends. Should I stop overthinking?
