Is this acceptable from the guy i'm talking to?

ive been talking to this guy for 2 weeks now and have gone on one day, didnt kiss him and it went great, texted me after and we talked/ flirted normally.. He has an instagram and an ex gf who uploaded a pic of him as a man crush monday, just thanking him for always being there and stuff. And yesterday night he uploaded a "woman crush wednesday" with her pic, thanking her for being there when his mom got sick and when bad things happened to his family. But he keeps talking to me normally... Should I be worried? He even asked me out on a second date :/
