<human>: Can you give me the gist of the text in a nutshell?

Me 21, him 27, together for 5 months.

We met through a dating site (sth resembling OKCupid) and it's been going pretty well. 

However, yesterday as I was doing some stuff at his place, I wanted to check the time. His telephone was lying nearby so I just pushed one button for the screen to turn on. It did, and except for the hour I saw "1 Missed Call from 'Katie 21 NYC'". Yes, Katie is my name and I'm from NYC. 

BTW, later I jokingly asked him how old I am and he thought that I am one year older than I really am. That's not the point though.

Is it weird that after 5 months he still needs a reminder from his telephone of how old I am and where am I from? I guess I am taking it too seriously, but I feel like he has so many girls interested in him that he needs to segregate them or whatever. It is quite stupid, sounds like a childlish problem, but it still bothers me. I don't wanna go snooping since I think it's not right.
<bot>: I still appear in my bf's telephone as "myname-myage-mycity" after 5 months relationship.
