Sometimes, people are not mad @ you for something you did.
They just, are disappointed, because they put much hope in something and because of what you did, all that hope is lost...
They don't talk less to you because they are mad, they talk less because they know now you can go perfectly without them... Everybody needs a person that take care of them... As soon if somebody found that person, all the rest can back off and watch you be happy with that one perfect person...
Nobody to blame... Thats just the way it is...
