I have a friend who whenever we talk in-person about hanging out on the weekend she always seems down/excited. Whether it’s coming over to my house, going out, trying something new, whatever she always seems interested. But when the time comes to actually make solid plans she either ghosts or flakes. Then when I bring it up the next time I see her in-person she always says sorry and she’ll make it up to me. I’m thinking maybe the way I approach her about doing things isn’t her style or just not working. For example, if I say on Wednesday let’s hang out on Saturday and she say “I’ll let you know” am I supposed to follow up or is she really supposed to let me know? Any advice on how to approach making plans better/easier?
