Trevorzero,
I know what you mean about friends who come and go and you are never sure exactly what the status is. I have always had this problem. I know it comes from my self-esteem because I feel that if they liked me they would at least contact me once in a while. But then they don't and I don't know if it is because they don't like me or if it is because they are too busy. But I usually find out that they are still around. I have found that there are different types of friendships. There are some people I talk to all the time and some people who I talk to maybe once a year. It just depends on what is going on in each of our lives. But I still battle with these difference and distinctions. When I was in school I saw these people every day, but now I don't talk to them as often. It can be hard. I hope you are able to contact you friends and they will contact you back!
