Inspired by recent comment By u/TheLaughingRhino:

People with good character who choose to be committed are the best chance anyone has to survive a long term relationship like a marriage.

How do you personally determine a man's character?

For example: How he treats his family? Maybe more specifically his mother and sisters? How he maintains friendships? How he deals with problems? How his previous relationships ended? How he deals with finances or debt? How he takes care of his body? His hobbies/interests?
