Dating a divorced man is not like dating a man who has never been married before.
Many women knowingly date these men and then get upset when he does not have the money or the time to spend on them.
Even if you only manage to see him once a week in the early stages, that's fine.
Plan dates in advance so he knows you're still interested, and keep in touch with occasional texts and phone calls in between.
Any decent man will put his kids first before your relationship.
