And I didn't find out until one of the guys she knows told me about it.
I was her very first friend when she moved here, and I did everything for her. I even went to the hospital emergency room with her, her sister and their dad because their mom/wife was dying, and I stayed there even when she did pass away and the coroner came in to talk to the family and told them the possible cause of death. I stayed with her after she left, because I was worried about her and I wanted to try and help her get through her mom's passing.
I helped her with her problems and hung out with her when she was down. We did everything together.
And she didn't have the decency to even pick up the phone or even send me an email and tell me she's moving hundreds of miles away...
I kinda feel betrayed because of everything I've done for her throughout the years...
I don't know whether to cry because she's moving or to be pissed off because she never told me.
You know, there's a good chance she just didn't know how to tell you. Sometimes it's much more painful to tell someone that you're extremely close to that you're leaving for good, rather than someone you aren't as close to.
I agree with Hugs. Don't be so quick to make assumptions about it. It can very difficult to tell someone something like that, especially if they mean more to you. Try talking to her about it... don't accuse her of anything, but maybe just be like, "So I heard you're moving? Where to?" and start a casual conversation about it, and then maybe ask her why she never mentioned it to you, then maybe you'll get some answers.

Sometimes it's really hard to deliver bad news, like being a doctor. It's hard to tell someone they have a terminal illness. Just like it's hard to tell a best friend that she is moving far away... don't be upset with her about it, just try to be accepting. Talk to her about it and maybe it will make you feel better. Also, it's not the last time you will hear from her. You can talk on the phone, text, email, IM, or even write an old fashioned letter to your pal. :)
My best friend told me last minute about her moving away when she did, reason because she didn't want me to be sad for our last days that she was leaving. I made sure that in that last day we had together, I made it last without the tears and the crying, until she finally really did leave.
As the others said, it's hard to say things like that to a close person, and so I wouldn't jump to conclusions.
I bet there's a really good reason why she didn't tell you so quickly. So don't get so bothered yet.
& I've had 4 best friends. FOUR! Move away. One to Wyoming, one to North Carolina, One to San Diego, and One to Sylmar. It sucks but you have to move on, like them..
She left already. Phone's disconnected, and the house is empty. =/
Never said a word to me about it. Will probably never hear from her again.
I know it was hard for me to leave my best friend behind when I moved back to nc. I knew she was gonna start crying, which was gonna make me cry, but I'm going back in July, for my dads wedding, and I'll see her then, and hopefully she'll be coming down here.
But like everyone says, maybe she didn't know how to tell you?
