Even if OP is autistic, it is still an issue that I can see being a problem. OP and his in laws have fundamentally different ideas on what good gifts are. Also, OP has shown an ability to interpret emotions being displayed, possibly better than the neurotypical family members.











You need to have a conversation regarding the feelings surrounding this with your spouse and what each others’ love language is.
It sounds like part of your spouse’s love language is gift giving, which may be why your rejection of their gifts hurts so much. You may view it as rejecting an object, they may view it as you rejecting their love.
I expect this to be a hard conversation, in part because it is a discussion on how you love each other.
