Thank you Redpepper! I know I need more activity and friends. I am working to change that, but the process is slow and difficult. I don't share easily when I am uncomfortable, and I don't have many friends in my hometown. Most of my friends are at least 3 hours away.
I think you hit the nail on the head when said I am jealous because I need more friends... to continue that thought, I realize I am not jealous of the FWB, I am jealous of my partner for having such close bonds with his friends.
As soon as I realized that, the scared voices in my head got quiet.
