Can I turn this thread round and ask the OP what does she think her sons think of her? Do they buy into what is, no doubt, a carefully curated version of herself that she presents to them. or is their view of her, however much they love her, of how mum was always fussing around thinking about what other people were thinking of her and Dad - and was always wrong!
We cannot shape what out children think of us, they make their own decisions and the things they remember and treasure are highly unlikely to be the things that matter to us.
So relax and leave your DH to be himself with his sons - and everyone else and you should also be happy to be yourself and stop second guessing what ther people are thinking of you as well.
