This isn't an AIBU and I felt uncomfortable with taking 1 part of the issue and turning it into one which I could've done, and made it very clickbaity, but actually the whole thing just makes me very sad 
and I just didn't want it to end up in the Daily Mail. I regularly post and have NCd and will lose specific detail to make myself and my friend less identifiable.
I think I'm being dumped as a friend.
Have known both my best friend and her now DH for a very, very long time. I was one of her bridesmaids when she married. In the run up to the wedding, everything very much revolved around my friend for about a year, but nobody minded, I didn't mind, I absolutely loved being her bridesmaid felt touched and proud and she wasn't a bridezilla or anything, but post the wedding she has found it impossible to 'let go' of being the centre of attention, making things about her/her wedding that aren't about her. I don't want to give the specific example but a tragedy happened and she tried to link it to the wedding in a superbly crass way.
Last winter, I became very ill and had to be hospitalized. Despite repeatedly reassuring me that she would be there for me THIS TIME if this illness recurred (I've been ill before and she hasn't been) she not only wasn't there, but was very dismissive, and sent me texts that read like they'd been written by a stranger. I still totally believed that she would at least be up to visit when I was discharged and not only did she not, texts petered out almost totally too, even when it was her birthday I only got a perfunctory one thanking me for my gift. I did try and address it months ago, but was told "everything's fine, just very busy etc"
To add insult to injury she has made the effort to meet up with another friend to "support" her with something highly trivial (imagine local baking competition) even though it's a further distance, I suppose because it's more light and fun I wasn't trying to "bring the drama" I just wasn't well! And it's just VERRRRRYYY fairweather of her. I see these memes about "dumping friends who aren't worth the energy" and can't help but feel that this is what she's done.
I literally haven't seen her since the wedding almost 3 years ago, and have now received an (unsolicited) list of pre-approved gifts for her PFB 
which I wasnt aware was even a thing!!!! And the worst thing is is that some of them aren't for baby but things more suited to a wedding list.
I just think she's disappeared up her own arse and I don't even feel like getting the baby anything now even though I'm expected to.
I miss my friend. It's a long friendship, but I not only feel like she's a different person, but that maybe she was ALWAYS like this and I just didn't see it til now. Have examples but won't drag on.
What would you do?
