Hey OP here. I wasn't expecting this to get posted! So just some background my crush and I were friends before this incident and we've had decent conversations. I have not been obvious about having a crush on him as I like to be friends with people and get to know them first off. That's why I decided to add him not to stalk him but because I considered him my friend... I honestly don't have any explanation for why he would block me but luckily nothing in our face to face relationship has changed. I also don't want to ask him about it because that was his decision and it's not really my place to question it.
