It's really hard to understand how people who were very close rather intimate friends all of a sudden become just a aquintance. When I think over it there has been lot of conflicting thoughts within me. No person can avoid anybody just like that but there must be some reason for it...may be they are busy sorting out their things...or could be that they are in a deep mess which they don't want you get into..there even can be some incident or action of urs which would have hurt them.
To avoid such problem, the first thing I would think of is to think from the other person's angle or come out of urself and look from a third person'r perspective. Try to understand the person's current situation and always think every relation with a positive approach. Handling relationships with a positive thought has the power of dragging ppl back into their happy moments.
