She gave him her number, too much??

A couple of days ago, my boyfriend (hayden) and his brother (Austin) went to get some pizza. The cashier apparently graduated high school with my boyfriends brother, however he didn’t remember her. When they called their order number, the cashier gave Austin the receipt and said “give this to your brother.” Her number was on the back of it. Obviously I wasn’t there, so she didn’t know Hayden had a girlfriend, s and so it’s not anyone’s fault for just receiving her number. Hayden ended up telling me right away which I really appreciated because he mentioned he didn’t want me hearing it from anyone first. I thought that was very sweet and I thanked him for just letting me know, and now it’s just been a joke and we’ve laughed about it...

BUT THEN

He goes into Facebook, and sees he has a friend request from this girl. They had mutual friends (my mom was one of them lol). Again, he showed me right away abs I just decided to block her. Was it dumb to block her? Hayden’s Facebook clearly shows we’re together. Most of his profile pictures are of us and his page says “in a relationship” with me... so I thought she took it too far by proceeding to friend request him? I blocked her just to prevent anything further because the “vibe” I got from her wasn’t the best one.

What do you think?? Did she take it too far? Thank you guys
