Confused

My crush and I where talking a couple months ago for a while but we had an argument and stopped talking because we had an argument but it was really one sided with me and he unadded me on sc but I was a bitch. Now I’ve recently started to like him again and can’t see the bad in him but like whenever I see him he’s always looking at me and liking my insta photos and sits where I can see him and he can see me at lunch. Any idea to what is going on ??
