i think you're seriously over-thinking this. she changed her mind and decided to talk about it to other friends, when she did the picture was probably easier to find or the friend insisted more than you. lower the expectations a bit, people will get annoyed if you have too much expectation. imagine, what are you going to say , " why didn't you show me the picture first, I thought I was your best friend and now I feel neglected" ? no, don't go there. let it go. you want to see people more, exchange more? be pro-active. make things happen. invite people, ask how they feel, take interest in their stuff, ask them about what's going on and follow up a few days later with follow-up questions, that sort of stuff , but be independant. independance radiates strenght.

is there anything at all that they may have only told you though?
