Left out in group convos

Whenever im with just one person, everything is great and we can have wonderful conversation.

Put me in a group of 3 or more and I always get left out! The other 2 or more people will always make eye contact with each other and never even acknowledge my presence.

When im more of the ring leader in a group (bringing different people together) I always make sure we are all talking, I make sure the other 2 girls talk to one another and that the whole group is included. I would notice right away if someone hadn't spoken or been recognized in 5 minutes.

I do say things and I do try in these groups but for some reason the other 2 ppl will always make eye contact only with each other and talk and act as if I'm not even there!

Anyone else feel this way?
