Best guy friend...

So about two years ago, this cute stranger started messaging me on FB lol we talked all day everyday and I started to like him, then he brought up his gf. I was like dang! Well, ever since then I just saw him as a friend. We've always hung out as a group of friends, never alone.

A group of us went to PCB in April, and I got a crush on him over there but as soon as we came back home, it went away.

Well, last night, we were having a conversation about me babysitting my niece and he goes "I wanted to kiss you since the very first time I saw you..."

I was like what! Are you intoxicated?? And he said no that he just thought of that and I told him about my crush on him in PCB and he said he was crushing on me too, that it was different over there.

Him and his gf are still together, she doesn't like to hang out with us though. She's not the "let's go out and have fun type." They're that "on again, off again" couple.

Anyways...I've been in shock since last night lol idk if I should shake it off or just keep that in the back of my mind?
