Left behind

I feel left behind... Don't know how to explain it, well I guess I do but don't know if it will go to far. I feel frustrated that I'm not as close to a friend as I used to be. I feel that I'm being pushed out and replaced by someone else. It's an odd step to move from single life to married life. Though Mikhail is my best friend I still feel as though some of my girl friends are my best friends and it hurts when they move on. I've never liked this much. Always have had a hard time with moving on. It makes me feel "uncool" for lack of a better word. I could continue but just can't... so in saying very little that makes probebly no sence at all i revert back to my original feeling of - feeling left behind.
