Hi wanttoask, and welcome to PC!

How you “should” feel doesn’t matter. You do feel hurt.

Typically, gifts are immediately opened and the sender is thanked.

My take on this situation is that they really don’t want or need the abundance of gifts. If they save them in a closet and open much later, they sure don’t need them. If they did, they’d open them right away and be thankful.

So, I’d stop sending the amount of gifts that would get put into storage. Just send less gifts, or bring them with you, so you and your gifts are appreciated.
