Aibu to have expected more...

[Miztry]

I have recently left my job, I had made one chum imparticular during that time; who had been a shoulder and a huge support.
I left a thank you card and a gift as a token of thanks and got such a blasé response.

I was hoping for a meaningful goodbye or a card but nothing. Am I being self entitled?..

@Miztry I'm so sorry you're upset that your long time work colleague/friend hasn't acknowledged your leaving in any manner.
It was very sweet of you to get them a gift to say thank you for all their support over the years. I'm suspecting you're a lot like me, someone who takes pleasure in doing things for people especially a sentimental thing that means something. (I like to let people know they matter & are/were appreciated nmw).
I'm am shocked that she hasn't even gotten you a card, or at the very least said she'll miss her friend at work. I mean WTH?
If you were just colleagues maybe we could all say yeah they weren't that close but from what you've said that's not the case so I understand your disappointment.
Unfortunately it sounds like she isn't interested in you now that you have moved on to pastures new.
Have you moved into a better job or promotion? Maybe it's a jealously thing. Either way I don't think YABU, you have every right to feel upset at your loss of a friend.
Although I don't think after the first non response I'd have apologised but that's just me.
Hold your head high & enjoy your new venture xx

With some people it’s just out of sight, out of mind.

You did nothing wrong, brush it off and move on.

It sounds like as others have suggested you've just got the wrong end of the stick with this relationship, and she perhaps just supported you as any colleague would (hopefully!) do during rough times and interacted with you as a perfectly pleasant work colleague but didn't consider you a friend, whereas perhaps you read more into it.

I'd just leave her be and if she wants to get in touch, she will do.

you did nothing wrong. in fact they should give you a present.
your reaction after giving the gift shows how important they are to you. and not very embarrassing.
i think they dont look forward to continue the friendship. its their choice.

I’m quite close to a fair few of my colleagues. It wouldn’t occur to me to get them a leaving gift because firstly, that’s organised by their team or management, and secondly, I would be staying in touch on facebook etc. so the work relationship is gone but the odd check in and chat remains. I think the gift etc from you was a little out of the norm.

Do management usually do leaving gifts?

I can't say I've ever seen someone give a gift directly to a leaving colleague. It's always the line managers that do a card and bottle of wine or something.

I think people manage goodbyes in different ways. We had a few goodbyes at work and there was all sorts of sobbing in corners going on. I'm not really like that and would probably seem cold to you. I think sometimes I process the change once it's happened. It's not that I don't feel sad but I think I compartmentalise and this week I've just been getting on with my job.

Some people aren't into sentimental speeches, but don't brush off your friendship. If she's the same it won't mean she didn't appreciate the friendship.
