How to weed out if a potential future partner has been abusive to someone else in the past and will be in the future with me?

No shortcuts:: only time will tell. Watch his reaction to confrontation, questioning and/or stressful situations. I suggest that any and all inappropriate responses are "red flags". Your "inner self" will direct your feelings; however, there is no "quick fix" diagnosis.

Abusive potential: If you are getting an uneasy feeling about a relationship it is good to pay attention. If you are cautious and move slow, a loving patient person will respect that. Abuse is often preceded by overly controlling behavior that may sound caring or protective, but serves the purpose of isolating you. You can always ask questions. And if the person has a history of a number of previous marriages-ask!
