So I’m in a bit of a situation, which is obviously why I’m here, and I don’t really don’t know if this is the right place to put it, but it’s worth a shot right? Pretty much, I’m sick of being the ugly friend, the one that’s constantly left behind or the second option. This has been at least the third time where I’ve liked a guy, and I’m pretty sure he’s almost liked me back, and then I introduce them to my best girl friend, and suddenly they completely forget about me and move straight on to her.
They use me as a connection to try and get with her, and because of the person I am, I feel obliged to help them, but I want them to like me, if that makes any sense. And I’d rather not bring it up with her, because it’s not her fault that she’s absolutely stunning and amazing in every single way, but it’s really getting to me. I just want someone to choose me, you know?
Anyway, thanks.

I know that this isn’t what you want to hear, but those guys don’t deserve YOU. You have special attributes that make your friend love you and men who can see past the sugar coating to you.
Right now, I’m just guessing here, you are in the age where the majority of guys who are looking are looking for just looks and the guys who want a good personality are too shy to ask or praying that the girl asks them.
What I found worked best for that age was actually online gaming. Men and women get to know your personality by playing a video game with you before they start drooling over a photo. Yeah, you’re going to run into some jerks, but when they are gaming they are much easier to pick out Imo, because they are the jerks yelling obscenities or making fun of newbies.
You will still have to watch out for everything you would in real life like perverts, older men who want stupid, insecure young women/boys for sex, and so on.
