New and saying hello

[~¤DG¤~]

How do you handle friendships?
My best friend and her fiance were good friends to both of us.
He hasn't seen them for a while but now he talks about possibly getting together with them.
I will admit, that bothers me, but I remind myself that acting jealous and insecure would be reverting back to the old me and I don't want to do that.

I trust my friends that they wouldn't bad mouth me, but it still makes me uncomfortable.
