Am i foolishly selfish?

Am i selfish or not. My friend likes the kid i've been talking about in my last 2 post. And i've known she has for awhile now and she is thinking about acting upon her feelings. Am i wrong to ask her to not to or am i just protecting myself. i undertsnad you cant help who you like. no one can it happens. but since she is a bestfriend and us highschool girls have that random little code to never date a friends ex/crush, should she not? ugh i don't know. Some may say i'm being a selfish brat and others may say i need to get over it. i want him to be happy inspite of me ( i maybe contridicting my self when i say this) but if its with one of my bestfriends. i don't think i could handle it. just tell me how it is and your thoughts on it. i just need good ole slap across the face with some real advice. and yes i have a boyfriend so it makes everything even more worse.

Wow, how long have you and your boyfriend been together?? i mean thats kinda harsh that your stressin another guy when your with him, its like what if he was watchin some girl?? ya know. if you want to be with other guys why are you stringin your boyfriend along?

We actually are about to break up 2morrow. si boyfriend wont be there anymore

She means ex or a crush. girl code, to save a friendship you dont date them. and knowing that, why would you go for him. you had you chance to be happy and gave that up. let your friend have her chance.

Think about this... you, while you had a bf, wanted to tell your friend to back off another guy, and now that your bf is out of the way, you want her to let you have him because?.... ya there's a hard one
