Is it considered stalking if I do this, and could I be caught?

There are ways , but he would really no reason for him to do so as yu are doing nothing illegal , being a bit nosy perhaps but oh well. Anything that is put anywhere with the intention of the public or part of the public to view it can not then come back and claim it was private and personal information , So good luck and God bless yoou as you seek your beau'ws heart
