Tell me about it, what else could more when you are there for someone and when you need them, they're not there. They're not there for you but they'll be there for others. It's like you dont even matter to them, at all.
 C'mon, tell me. How someone can be so important in your life and you are just one of his/her closest friends.

It's like you don't even dare to call his/her your best friend, your bff. Because he/she might not think the same way as you do. You're afraid that if you put in a lot of effort in this friendship, it might not even work out in the very end.
