Flirting

Guy who flirted with me didn’t follow me back and I don’t know what to do?

I went to a gay bar with my best friend where he met another guy and started talking. The guy my friend was talking to had a brother who didn’t drink but was there to take care of him and making sure he was safe. So he introduced us and we hit it off immediately. He was super flirty but kinda shy, or so I thought since sometimes he would blush or couldn’t hold eye contact. He also rejected other girls that approached him and got annoyed when another guy tried flirting with me. We ended up dancing and almost making out but nothing happened in the end because his brother got too drunk and he had to rescue him lol. The thing is that I decided to follow him on Instagram the next day to maybe talk and meet but he didn’t follow me back. I have been trying to think what may have gone wrong but can’t come up with anything. He’s a professional football player and his account is kinda focused in that (he only follows like 100 people) which most of them are guys and other football players. Some of my friends think he didn’t like me, others think he didn’t see it, others think he just doesn’t usually follow people. I know a following is not important and doesn’t mean anything but I wanted to talk to him and now it feels awkward to send him a DM without his follow back, like I would seem too desperate. The friend who was there that night thinks he’s definitely into me but I don’t know how to approach this guy since I’m kinda confused. Any advice on how I should act to not screw things up?
