If i’m honest I dont really have a strong opinion on it, we don't know the context of what went down, or the history (I don't know anything about him tbh).
What I will say though is that i’m surprised you can be charged with harassment for shouting down the phone at your partner. That detail makes me think he really tried to get Jolanda to leave, asking Gigi to back him up, she refused and and he obviously lost his temper. We don't know the severity of this, we know he's said things to her, but we don't know how she behaved towards him. Again I feel I need to point out that i’m in no way excusing him, I'm just being realistic in that it usually takes two to have a row. I think if he had really done harm he would have had a prison sentence or similar, but I think anger management is a positive thing, clearly he needs it.
Because of all the above I am inclined to think it's been blown out of proportion and dramatised. He didn't go looking for a fight, he’s lost his tit and he's facing the consequences.
Yeah tbh this is it, its just reality. Anger management is needed, but let's not make it something it isn't.
