NOT giving him anything would be a definite 180 for me. I've always gotten him something...even if it was "just from the kids". It makes me feel bad when I don't give someone something, that's how I feel. I don't care if someone gives ME something or not, I like to give things that make people happy. And he has said in the past that I am the only one who has ever given him things he really & truly wants. And, having witnessed what others have given him (yes, even OW) I do believe his statement. He has some particular interests and I've always focused on getting intriguing, hard to find gifts that genuinely make him happy and are in conjunction with his interests/hobbies. It's really not that hard and you would think anyone that knows him (duh, family and OW included) would focus on these interests, and from my POV, they never do/have.
And, oh boy, I don't want it to sound like I give gifts to earn love - that's not it at all. I happen to like putting a smile on someone's face and knowing that it made them happy.
