Is this ok for a guy to do? Options

[BlackCelicaGT94]

Ok so i was on my way to the gym and I saw a honda and we started playing cat n mouse a bit. I give him the "whats up" nod and then turned off to go to my gym. I come out an hour later and theres a note on my car that reads


"Nice Little Race! Call me sometime. Oh and next time u wont have to roll down the window"

so i call him and we chat for a few but he had to go to work so he said he would call me later. Well i text him back n forth a few times and i ask if he has a g/f and he said Yes. been with her for 3 years. I said what are u thinking leaving ur number on a girls car? and hes like well u seem fun to hang with and im like well yeah go make ur friends thru ur work or something but dont go chase down a girl. And he said he was strictly lookin for friends but it baffles me that he would go so much out of his way to try talk to me.

I told him i cant be friends with someone who can do that.


So is that ok? If u guys were/are in a relationship would u go leave ur number on a girls car?
