Hmmm, things like this have been going on for ages and always will do. The fact that they are talking behind peoples back shows their insecurity. I dont know if they realise, but those same people will be talking about them too.
I think your friend will still be your friend, its just that they got put in a situation where they felt pressured into joining in. maybe the so called friend isnt as strong as you.
I dont think some people actually realise they are causing hurt. It makes it much harder when its someone who is supposed to be your friend.
Also I think a lot of women are emotionally unstable at this time of year as they see their friends etc, getting gifts and cards.
I know most women like all this equal crap, but deep down they are still women and like company and gifts and like being someones wife/girlfriend...
