Just need some support / advice. DS came home 4am shouting at his gf, not the first time. He'd been at work (restaurant) then to a club, Obviousky drank a lot. I woke up, tried to intervene and he started on me. He's a big lad, was throwing his weight around, slamming doors, swearing at me and his gf, couldn't even speak to him, wouldnt listen. I'm a single mum and have two younger DCs, thankfully asleep through all of it. Long story short, I called the police, felt I couldn't handle the situation, triggered because his father was abusive, furious that he was behaving this way, mortified that my DS was being so abhorrent to his gf. They took him into custody, I didn't expect or want that. Just wanted some back up, some authority. Now if course I'm wracked with guilt. Worried how it will affect our relationship but I will never forgive myself if I've raised a son who intimidates and threatens women. Is it genetic, alcohol, or is there sthg I can do to stop him from repeating history? Was I wrong to call the police? Just mortified.
