And I'm posting on chat, just to get some perspective. My SIL and me both share the same birthday (today, 17th February). I love my SIL like she's my own sister, and regularly send her emails/presents/messages as she lives in north America. When it's our birthday, we'll always email snd wish each other happy birthday, gifts happen when they happen. My issue is my BILs, (husband's brothers).
I always organize buy/send gifts and wish BILs happy birthday, but they don't do the same for me, even a card, or an email. This year they (husband's brothers) jointly paid for SIL to have a spa day (which she totally deserves), but I don't even get an email, card, text or anything...it's like I don't exist or matter. Just feeling a bit sad, I try to not let it get to me, and just expect to happen, not sure what else to add, just feeling wistful.
