What would you do if you were given a gift by your child who won't chat on the phone or see you IRL?

If you were given a gift would you send one back if the sender was giving you the silent treatment most of the time, only answered selected messages and didn't pick up when you rang them?

What would you do?
My son who lives locally sent us a lovely gift for Easter, but we haven't seen him for a few months. Question is, should I ask why and risk straining things further or just send an expensive Easter gift back and give up hope of seeing them?

My husband says not to send a fancy gift back because we'd already bought eggs and such intending to gift them when we saw them... but then I think not returning a gift is rude? He says presence is more important and that I should tell them that- and I want to but am worried about putting too much pressure on.

It doesn't make sense because in messages he has shown more interest than usual in other members of the family- he's just very distant about his own family and won't even discuss his kids for some reason. I do miss them and don't want to make things worse. Some people have suggested head games. He may be playing head games, but I don't know why he would- or he may be struggling in some way?

I appreciate any thoughts or ideas. The last time we saw him everything seemed positive and we had a good time together. It doesn't make sense.
