What is an acceptable amount of gifts to get your significant other?

I got my wife 3 gifts for Christmas.3 Expensive gifts.and yet tonight while putting presents under the tree I see she got me 7 gifts.It makes me mad every year.I tell her lets take it easy on the gifts and she ends up getting me a ton of things while I get her usually like 3 or 4. Then she “jokes” about how there are only a couple of things for her. It makes me so mad I want to just take back what I got her and get her nothing. I’m an adult,I really dont NEED anything.One small gift is fine,I’m not going out and buying her 20 gifts.This has gotten out of hand.
