I felt a bit jealous but a bit hurt when he yelled and told me to go somewhere else

So me and my crush been knowing each other for over a year ish, we have flirted , teased , known each other, he goes out of his way to see me, help me and be there for me as well, we also make lots of eye contact, glancing or smiling at each other while making eye contact while passing each other, he held my hand as well.

But like recently I got upset with him because I saw that he left with someone from work earlier. So I low key got jealous so i couldn’t really face him I was a bit jealous, I kinda avoided him for a day or two till I was ready to see him I wanted to talk to him and see him but when I tried being next to him, he kinda yelled at me to go somewhere else then I asked if I did anything wrong then he responded back to me with his soft voice,I just listened, I got upset and just left.

Then later he took his lunch where I usually training people then after that he kept coming out of his way to see me and help me as well.

Why would did he try to push me away when I tried seeing him again then he kept coming to see me a lot of multiple times when I kinda wanted to avoid him again after him yelling at me?(he knows that I don’t like people yelling at me)
