Maybe your brothers have more to offer than you give them credit for. As long as they are happy that is what is important.
Sometimes I think I was lucky to have married my wife.
Actually, my sisters-in-law knew that my brothers were loyal, and good providers and cared for children. But as they are also opinionated, bossy, flatulent and overweight, they have not always been easy to live with. Good thing everybody has a sense of humor. No divorces at all.
