Why would a fuck buddy get jealous?

[Anonymous]

A few days ago I told my fuck buddy before we hooked up that I had started dating someone (but we're not official/exclusive yet) and he was

-asking to see pictures of him, his name, and where he was from
-calling him a pussy because he hadn't had sex with me yet
-asking if I send nudes to him
-telling me that I'm the best he's ever had and I'm the only girl who can make him cum
-asked if I wanted to adopt his kitten? I told him to ask his friends and he said "no i'm asking you"

A few days after he asked for nudes of me and he has never asked for them before in my 8 months of seeing him. Then he was asking when I could go over to hook up even though we just did 3 days ago.

I told him I would keep seeing him until (when/if) me and the guy I'm dating become official.

I don't know why he's acting like this? I feel bed? Any advice and opinions would be appreciated

Oh geez. I don't know, some unknown guy has just unexpectedly come into the picture and is threatening to take his source of sex away from him. Maybe that could be why he's so jealous.

Everyone has feelings you know.
Maybe he is jealous because he has feelings for you or he likes u i think.

He probably just developed feelings for you and is getting jealous. Just watch your back, jealousy can get worse if you don't confront it head on

He's attached to you and probably feels weird that he's not alone! Territorial fucks!

[niletaki]
