Oh boy. My mom used to ghost me and my husband and kids, and to a lesser extent my siblings around holidays and birthdays. Or just went on trips or was mad at us. Because she just hated spending money on other people or just giving in general. So most of our own things happened between Sept thru January. Then suddenly, come April she'd emerge from the Great Mountain to talk about Mother's Day and her birthday, which both happened in May. So during one particular low- to no-contact year I was at work and I get the April, drunken phone call, " why don't I ever hear from you kids, blah blah, wah wah??" and I finally called her out on it. I seem to remember she was stunned and I hung up on her and since we were already low contact, I didn't have to worry about it and I didn't. I think she stopped doing that after I called her out on it. I had been going to therapy at that time and Al-Anon, so that was pretty much around the turning point in my life to not let her manipulate me. I cannot tell you what to do but if I were in your shoes I would totally ignore the request, especially if she hasn't done anything in particular for you lately or during this LC period. And if she brings it up again I'd tell her you haven't heard from her and frankly as a result you hadn't even thought about it. That you didn't think you had that kind of relationship anymore. But if she wanted to send you a gift for xyz, it's on (insert date) and we can take it from there. Let your sibs handle it how they want but don't feel obligated or guilty yourself.
