How to tell best friends there ignoring you ?

Jacki and luci

I knew jacki since 4th grade and luci i knew since 6th and we all became really close friends but last year (7th) they started to act diffrent . When me and luci hangout or me and jacki do they acts really nice and talk to me like if i were there bestfriend but when were together both ignore me i told them before they act diffent when there together but i think they took it as a compliment. i only brought it up once but i dont want them to start ignoring me more. When ever were walking in the hall way im always in the side never able to hear them beacuse who ever is in the middle moves there head far out so i cant hear. I feel like the third weel when im around them I tried brushing it off and hope it would get better or back to normal ( normal being we all act like bestfriends and dont ingnore me ) . They are great friends when one of them isn't there but I want us all to have fun together not just them. it hurts me inside seeing them have pictures on twitter and Facebook having fun together and also having conversations and inside jokes i don't know about and saying them infront of me . I love them and I want to talk to them about it but i don't know how to say it . I don't want them to just ignore it , take it as a compliment , or get mad at me . Im also scared to tell them because i feel like they'll just pity me and talk to me in another different like someone they HAVE to talk to or babysit.

Go up to them, say, "Hey, you've been ignoring me."
Simple.
