I have seen something similiar here before and being Christmas time.
The other issues - feeling as though one is being 'bought' or not feeling respected enough, or feeling uncomfortable accepting those gifts - those are separate issues to address. If you truly feel the gifts are not being sincerely given without an ulterior motive - that's a personality or relationship issue that you must examine on your own - with or without the gift-giver - because the gifts themselves are not the real problem.
Just my 2 cents.
someone who enjoys being generous. I am so fortunate to receive such joy when I receive a gift.
We may say thank you, or may say we are not able to accept them. Depending on what they are. Flowers are beautiful and always loved by men and women alike. If someone gives you an expensive gift and you are not "ready" for that, perhaps either the person can afford them and wants to be generous or maybe they are trying to "buy" your affection, you will know. Perhaps they are just excited to give. Hopefully not breaking the bank! The gift can be large or small. I would be leery if I knew they couldn't afford them.
I guess that is as individual as the person.
