Boy Bestie acting weird

So my boy best friend, I feel like he's being doing things to get a reaction from me and it's weird as hell💀

For example:

He messaged me saying "You're gonna be so mad but I've met this girl and I kind of like her" its like he wants me to be mad that he's met a girl?😂😂

He also likes photography and was sending me photos he's taken and he sends me a pic with this girl and then he messages me saying "This is my best friend down here atm the other chick that I was saying might come to Bali with us, I love her so much oi she’s so cool 😂"

"But your my OG best friend my day oner yes I know🙏 she calls me best lol"

I messaged him saying

"You do not have to explain yourself to me, you can have more than one best friend I'm not gonna be upset"

He replies saying "Then there’s me if you EVER told me you had another boy best friend I’d be like HOW did this happen you're my best friend, I'd be so mad"

It's like he wanted me to be angry that he has another girl best friend and idk I'm finding it kind of cringe that he's doing this💀

Or am I being dramatic😂😂😂😂😂
