Is there a term for this?

Have you ever had that awkward feeling with someone you use to vibe with all the time?

For example, say you met someone and you two clicked and would talk all the time and consider each other friends, but (let’s say) during summer break, you guys didn’t talk/interact much and when you go back to school and see that person again, you guys don’t vibe anymore and there’s a weird/awkward feeling that makes you repel against them?

Is there a name for this? And why does this occur if you guys had a lot of chemistry at one point?
