How not to be the third wheel!?

I am a teenage girl and my 2 best friends have begun dating. I feel terribly uncomfortable and hate that they are together and that they didn't even think of my feelings. However they seem happy and I am trying to be supportive. I am having trouble dealing with this and really need advice please!!!!!!|||Just act like you are having fun WITH them. They can always have their alone time together. You don't have to be with them ALL the time, but when you are, have fun, ignore the fact that they are dating. If they really are your friends they would want you with them. :) xx|||Get a boyfriend.
