It'll pass, don't worry! Don't focus too much on "waiting for him", if it's bound to happen - it will! A lot of girls were/are in the same situation, right now it feels like you might never meet anyone else or it'll never pass, but trust me it will. You have to occupy your mind with other things, go out, do what you like and stuff like that. Don't snap/message him, you see how every time he's busy and it just breaks your heart a little bit more. You have to be strong and wait it out. Good luck, you'll be alright!
