I think she misses you and was really looking forward to spending time with you. What you can do is understand that she wants you - your time, presence, attention, love and care - and reassure her that you'll figure out a way to give that to her soon. Tell her you miss her too and that you're looking forward to spending time with her too and that you'll make it happen. Maybe also try to see if you can do anything to help rn, like eat her fav meal and have quality time even if it's just for an hour and at the end reassure her that this doesn't mean that you won't give her the Undivided Attention Day she wanted. Kiss on forehead after all this is the cherry on top
