if he is your boyfriend & your sure you know enough about him already then its fine & should be safe to date him, but if you recently started know ing him then its best to get honest information about him first-either from a shadchan that knows him or from someone else that knows him for many years-before starting to date im seriously & heading towards marriage.
May Hashem guide you in the right direction & send you to the right people for advice on the issues needed
