AITA for feeling hurt

so my girl and I just finished having sex, she looks at her phone and has a message from her male friend, cool he’s a good dude and I’m not worried about him, that’s not what it’s about. he says he’s driving and falling asleep and to call him so she calls and after a bit gets thru. she found out he was okay and was at work. I’m waiting for her to just come lay down so we can go to sleep and she stays on the phone with this dude while I’m just there waiting. and when I said something I’m in the wrong. am I crazy? we just got up from fucking and you wanna immediately call another dude and telling him I’m drinking an energy drink like you gonna talk to him all night? do I have the right to be annoyed? I feel like I do.
