Some indications may imply to the tendency to violence such as,

being angry in general, being intolerant, always blaming other people and  having bursts of anger,

not taking responsibility, not accepting his own faults,  blaming other people for everything,

having a sexist attitude, having very rigid judgments on how women and men should act,

acting in a controller, oppressive and restricting manner, having  the desire to control the places you go, the people you meet and your life decisions,

getting cross, sulking, exploiting emotions and self-pitying if his wishes  are not met,

acting as if the world revolves around himself,  always expecting you to hold him and his expectations before yours,

not respecting  and violating your physical, emotional and sexual limits,  knowingly and forcibly doing the things which you told him “not to do”,

showing extreme jealousy and presenting his jealousy as normal.
