my best friend is his best friend., what to do??? Options

[na-nancy]

so yeah, my very best friend is also my boyfriend's best friend as well.
and lately, they've been hanging out together and it's nice to see them to.
i don't get jealous, but i just wonder sometimes...
like he doesn't laugh that way with me like he does to her.
and i always wonder..'what if he ever leaves me for her?' =(
or i never have that much fun with him like they do. =(
i know, i'm being very pessimistic. =(
but whenever i'm with the two of them, sometimes i feel left out when they're
talking or joking around...i really do. It's like sometimes i feel isolated from them.
he's a great guy, like even when i'm with them he always checks with me and asks me everytime, "are you okay?" or give a little shrug or notice that he knows i'm there =)
i never told anyone or them my feeling. but yeah, of course best friends spend times together too, i definitely understand. they're like brother and sister best friends and i definitely have no probelm with that. before dating him he was kinda like that to me too (we were friends since freshmen year - now sophmores)
yeah, but i don't know..i just think and feel like this sometimes...
any advice???

Since you guys are best friends, all three of you I think its just all in your mind.

i just say just have a mature conversation with him.
Tell him whats up, even if this is something small, it can be become something really complicated later on.

He might get mad that you're thinking like that but as long as you get your question answered you won't think like that anymore right?

goodl luck!
