Hi A.,
Oh how I know what you are going through, only it isn't about "play dates". I have lived in Colorado almost 4 years. I have tried to make friends, and have been a good friend and neighbor, only to be "used".
My neighbor who has called upon me 3 or 4 times to watch her 4 dogs, feeding and medicating them now does not even return my e-mails. She borrowed several dvd's from me and has not returned them even after I have sent her an e-mail asking her to just put them in my mailbox if she is too busy.
Another so called friend (used to deliver our mail but got fired) would e-mail me and send forwards, and occasionally we would go out to eat, or shop at Sam's club. She offered to evaluate a horse we were looking to buy, (being she said she had worked for Wayne Newton, and knew Arabians.) We set up the appointment, she never called to cancel and now does not reply to my e-mails.
My friendship group that meets a few times a month, are lovely people, and I love them, but I guess the busy-ness of life keeps them from wanting to e-mail or call (despite the fact my husband and I have had two barbeque's to which some have attended.
My advice to you...let your friend make the dates and hold her to them. If she continues her disappointing you..."move on". I know there has to be someone out there who will appreciate you and I for the friend we are trying to be.
Blessings,
C.
