Hi Sunflower123, sorry it took a minute to catch your post. I see that today (Monday) is wrapping up -- did you end up giving him the card and gift? If so, how did that go?
Am I remembering correctly that you two are still in a relationship (i.e., it's not that you've broken up and are trying to reconnect)?
Sometimes it can help us to reframe our choices away from "how will the pwBPD react" as, like you mention:
I feel like if I do something he'll get upset and if I don't he'll get upset.
If his response weren't a factor, what would you personally want to do, for your integrity, to match who you are?
