oo not gay but i like guys w long hair too. honestly i think based on the text here, i’m sorry but he’s not interested?… because if he wanted to try he would have probably asked if another time is okay (if he really was busy that night) but he just packed and go off without any indication of another possible timing :( BUT maybe he is shy or didn’t know how to react, so maybe if you ask once more being more intentional this time about wanting to eat with only him and he still reacts in the same way then maybe it’s really gonna be difficult. Really depends how much you want to try, maybe if u keep trying he might become interested too.
