Do you think I'm stubborn?

I think, in life, you need as many friends as you can get. Sometimes expectations of how those friends should behave interfere with just enjoying the person for who they are, faults and all. I wouldnt worry too much about the other girl and what they are doing without you, thats between them, concentrating on something you cant understand or control can eat you alive. Try to focus on yourself and what you are doing. Plan fun events and invite your friend so you guys can get some one on one time and possibly re-discover each other. Try to not have expectations and tell yourself you can have fun with or without this person. Invest time with other people too, this person's friendship isn't the be all and end all of your life. Losing a friend can be like grieving for someone who has died, it's tough and emotional. Since you guys have been friends for so long it would be nice to grow old together and one day be sitting on the porch; grannies having a laugh about all this.
