Is it normal for me to be this obsessed with this guy I keep talking to?

I know this guy from high school and me and him used to date/talk. These past few months him and I have been texting and last week he got annoyed at me because I was getting jealous of him being friends with this girl that we both know. He told me
"this is getting annoying, I can't do this" so l blocked him for a bit and deleted the text message convo. Then I unblocked him.

Then today I see a instagram story posted by a different girl it's of the guy that I'm talking to he's like working at a bar (I don't know the girl who posted this at all) but the guy l'm talking to hasn't been responding to my texts like literally all week.
So it's irritating so I responded to this girls story. I know that this isn't normal. And I want to get your opinion on this/ what I should do. I have feelings for this guy still. Could he just be preoccupied with school/work? In high school he used to play football and I would wait until after he was done with practice or a game to text him. and I thought it would be different in college and I thought he would start paying attention to me.. I'm not sure what's going on. If this helps him and I are 22.
