i introduced them and now they are best friends? :S?

[BA BA BANANAS!]

im friends with these 2 girls.
one i go to school with since we were little and the other ive just known for a long time and shes my best friend.
a few weeks ago they both came over and we all just hung out,
now they hang out just them two and don't even ask if i want to join.
i don't want to sound jealous, its just ive lost some close friends this way in the past and i really don't want to lose them too.
i think its great them being friends but it just makes me really sad that now they are best friends and don't even ask me to hang out.
should i talk to them about it and what should i say if i do?

i wouldn't talk to them together. talk to the friend you trust the most. just invite her over or something, and if you feel comfortable ask her why they haven't invited you. another tactic would be to ignore them altogether.

Just tell them you feel left out.
Say you think all THREE of you should hang out.
