So my boyfriend and I are getting along pretty great and stuff and we haven't had many issues in the past. 

So one night I jokingly get on his phone to message myself (we do this a lot to each other) and I see a name at the bottom of the text messages. Let's call her Jan. 

So I asked him "who is Jan?" and he said "no-one" 
Thinking it was a relative I opened the text. We have previously agreed to going through each others phones so again this wasn't a big deal. 

It's some girl at our highschool and she's messaging him stuff like "can I be your Valentine?" "I'll be whatever you want me to be" "you seem so sad all the time" (my boyfriend has sleeping problems and always looks TIRED not sad.) 

So I was like what the hell babe? Who is she? How do you know her? He said some girl he tried being friends with but it's not working out. So I was like why? You have (Kaitlyn) and (Jessica) and all your guy friends? 

His replies to her text were "I'd rather just be friends." "thanks" "I already have someone" 

So I messaged her saying that he was taken and please don't message him again and then I blocked her. When I read the texts they were days old he never told me? So I was super upset. 

So AITA?
