AITA for catching an attitude and leaving?

Me and my boyfriend been together for 3 months now, have dated for longer. I’m not photogenic so we have no pictures together because I don’t ask. We hung out tonight and as I was leaving, I was like “let’s take a picture but on ur phone because mine is dead!!” He responds by saying “I’m tired I have to go home” and I said “it’s only gonna take a second or 2 really” and still kept declining making more excuses. I got upset by this because why is it a big deal if we use 2 extra seconds to take a picture? He even did this the very first time I asked and it’s just weird. I could understand not being photogenic, but using bs excuses to not have to take a picture is weird, especially if I’m supposedly your girlfriend.. so I got upset and left. He yells out for me to come back so we can take the picture but at that point i felt embarrassed and just kept going, it felt forced because i had to get upset for you to do something so quick and happy and quick your gf happy
