You should check that he's very patient, not violent, a good guy.
You need to go father than that, though.
Choose a man who:
- shares the same values as you and has the same priorities.
- treats you with respect.
- has a good job history - This might seem cold, but it is important or you might find yourself supporting him.
- encourages you as an individual
- is not selfish
- etc.
Do not base your selection on emotion alone. Marriage is meant to be for life, so take the selection of a husband seriously...and use your brain!
