Maru, he clearly knew how to undermine her on an emotional level as underneath the cheeky chappy facade he's manipulative narcissistic and blatantly emotionally very intelligent (not academically intelligent) which he uses negatively to his advantage to distress, torture with constant wind ups, pick on weak spots, cajole, humiliate, undermine, charm and reel in emotionally (he is very successful with the girls on EXOTB despite there being better looking guys), getting girls to do sexual things with him early, then cruelly ditching them without a care :rinse and repeat. He's a highly dangerous nasty creature, devious but he does make good tv.
The fact that he was able to get one over on a 47 year old so called feisty strong mob wife is very telling. He enjoyed the challenge of bringing her down a peg or 5 as she set her self up as this strong woman. I can see he probably enjoyed destroying her. He never picked on Katie as she was already unstable and weak.
The fact that he apparently thought in EXOTB it was OK to throw a knife at someone, even if it was Gaz Geordie Shore, is shocking. He is probably a sociopath (getting away with it as loads of females seem to fancy him and excuse his appalling conduct as if it's nothing wrong) but Renee needs to move on quietly as reliving and outting Bear's horrific antics will probably cause her distress.
