Does he have a crush on me?

Hi. I'm a sophomore girl who's really confused about this one guy. So this guy is a senior but also a swim team captain. We've been knowing each other since I was a freshman. We are just good friends but I didn't have any feelings toward him. Plus, he had a girlfriend back then. But nowadays, he's making me confused.
First, It's always him who starts the conversation first online and offline almost everyday. We mostly talk about swimming and other things too. He also tells me things that he's stressed about and things that he doesn't share besides to me. He encourages and compliments me a lot too. one time, he told me he loves the way of how i can take jokes. On some of his chats, he added some winking faces too. On Facebook, he likes my posts, pics and profile pics.
After the swim meet, he decided to grab something to eat with swim team members. He made sure I was coming. And the other thing is that when we arrived at the restaurant, we had to split ourselves into groups since we couldn't put tables all together. I was sitting with my friends when he came over to join. There were other senior guys (plus they are his friends) but he came over to my table to eat with me instead.
We had a day off from school and turns out guys were having their own training. Girls got upset of how guys didnt tell girls about it. But he texted me and asked me if I was willing to join only I couldn't go cuz I had my own schedule. But my friends got upset of how he didn't ask them.
Help?
One time, we met each other in the hallways before going to the practice. I was waiting for my friend to show up, but I decided to go by myself as she didn't show up for a long time. Then, it turned out he was still waiting and turned out he was waiting for me.
We always have these inside jokes that we share and laugh about too. Being around with him just makes me feel so happy. I'm just wondering if he's just being nice to me or if he actually started having a crush on me...
Thankfully he has no girlfriend at this point
