Do these signs say a guy likes me, guys only as I need a perspective from a guy

So I’m guessing some guys will be on this group, but probably not a lot. I was wondering though, guys only, if a boy who has a girlfriend and actually says he has one, texts you things like I have muscles, what do you look like now, I play sport blah blah, do you think he likes you or is he is just keen/flirts for the hell of it. Cheers
