Make sure he has scars on on the back of his hands, it's a good sign he has experience either fighting or making things - creation is an act of selflessness and bruised knuckles are a good sign he knows how to defend himself. You've got too much soul to be handled by someone who has never been passionate... Rough palms are better than soft ones, they have been salted by this earth and made into leather. Callouses are evidence he has lived, that he has broken skin and been in pain over and over and over again and still came back to the source of it. People rub against each other. Don't marry him if he can't handle even a little blister.
