it sounds like he and dom would get along pretty well! dom is super proud of his pureblood status and enjoys mingling with the "right sort" of people, a total charmer but utterly faithful to his wife. his involvement with the death eaters is very under wraps so it doesn't affect his career plans. maybe they meet a lot at various social engagements?
edie would be absolutely taken in by his charm, though i'm not sure how they could cross paths. she's a pureblood who doesn't much care about it, and works at the ministry in a pretty dead-end job. if anything, she's super friendly (read: naive) and will happily strike up a conversation with anybody she meets, so they could have a random encounter?
