"tortoise I thknk you are very perceptive, there are lots of things I am good at, I am very clever, a talented seamstress, a developing gardener. Maybe I need to show love to dp using a different talent, I wonder how he would look in a dress. "
I think perhaps another way of showing love would be easier, because food is so loaded, but I do also think that this is about giving and receiving love overall.
My mother, who reads self help books and goes on courses and whatnot, talks about Love Languages. Her last relationship faltered partly because he was a 'show love' person - put up sheds for her, fed her cat, etc., whereas she was an expressing love person, and used to wonder why he couldn't just say I Love You or You Look Nice. She knew it was a difference of style, but it's really difficult to accept a style of love that's so different from your own. She is proud about being independent (raised us alone and hasn't lived with a man since my Dad) and all the little favours and tasks that her boyfriend did just made her feel patronised. So she'd get defensive, or try and avoid needing his help, and then he'd feel rejected and withdraw, and then she'd feel unloved, and it was this whole thing.
I don't know about Aspergers, but I wonder if part of your issue is about this; for whatever reason he finds it very hard to accept gifts, whether they be food or jewellery or etc.
How does he show you love? Does he tell you sweet things, or fix things for you, or is he physically affectionate, or what?
I'm no expert, but look at the ways he gives love as well as how he receives it. Not that you should adjust your methods for him, but it might be a lever to get him to start seeing it your way.
Alternatively, you could come be my wife. You sound rather wonderful.
