Mother’s Day for my boyfriend ✨🥺

So my boyfriends mum died 6 years ago, and every year on Mother’s Day he shuts himself off, he tell me not to speak to him because he’s snappy and all in all he hates Mother’s Day and can’t be around him on that day.

I wanted to do something special and memorable this mother’s days, something to do with his mum and him.

Does anyone have any idea of something sweet to do for him ?
