I don't know if I'm being unreasonable or not. My friend moved not so long ago (within the same area) and I sent a 'congratulations on your new home card'.
I've just moved to the other end of the country and I haven't received anything from her. She hasn't asked for my new address, and generally seems uninterested in the friendship now.
I know it's just a card, but I feel like it's symptomatic of a wider issue in our friendship, sadly.
I don't think I'd be so bothered if she didn't keep tabs on birthday/Christmas/etc cards from other people when she feels hard done by.
