Quick note -- all the abbreviations in use here can be confusing. The typical usage is BPDh, not hwBPD. There's a
Guide to Abbreviations here.
When we were separated last year, father's day fell on "her" weekend. I was not happy about that, but I also didn't want to turn it into a crisis, so I reasoned with myself that I could simply celebrate a belated father's day. So I arranged for brunch at a nice restaurant the following weekend. (One advantage of years of trying to live with BPD is tremendous flexibility around negative events and the ability to recognize when emotional regulation is to my advantage!)
For mother's day, I "helped" D10 buy a gift and card, then left them to it.
This year, we're in the divorce process but do not have a holiday schedule. The regular schedule has D11 with me for mother's day. BPDw actually approached me and made a reasonable offer for a swap. The fact that she could offer to barter instead of making threats and demands was a huge milestone. So, I swapped days with her, and D11 will be with her for mother's day and me for father's day. I'm planning on a brunch again, and once again I "helped" D11 buy chocolates and a card.
Fortunately, BPDw hasn't expressed any interest in trying to use the holidays to get back together with me, so I don't have that issue to contend with.
I'd suggest you make some plans for your holiday -- you may have to modify them to accommodate what fits your living circumstance. A nice breakfast out rather than breakfast in bed, for example. If you choose to offer your husband a swap, do so out of the goodness of your heart and your sense of what's right, and don't expect any reciprocal generosity. And don't let him use sentiment to pressure you into something you don't want. And do try to give yourself some emotional distance from all of this, so if the holidays are all blown to hell by failed negotiations this year, you can always have "belated mother's day," just like I did last year. You're the emotional adult here -- you don't have to let a ruined Hallmark holiday destroy you.
