Name changed for this one - I am a regular poster who has given advice many times previously on these boards, but am stuck with what to do in the situation I find myself in. Adult dd, 24, has recently moved into her own home with her boyfriend of 4 years (6 months ago). Her dB had lived with us for the year previously as they were saving for a deposit. She recently confided in me that she has started seeing a councillor as she has been having panic and anxiety attacks. Further digging and she added that her dB has been attacking her physically when drunk. He is a social drinker and goes out with his friends, or with her, once a week, and although normally a quiet unassuming person, when drunk he starts insulting her, she challenges him, and he then attacks her, pinning her down and actually bruising her. Afterwards he is apologetic and treats her like a princess, promising it won’t happen again. I have told her this is abuse and she needs to tell him to leave - the mortgage is in her name only as he comes from a dysfunctional family whereby he took out multiple loans to help his mum with an addiction she has. His credit score didn’t allow him to get a mortgage. She said she doesn’t want him to leave, as she wants them to work things out together, neither does she want us to tell him we know or involve ourselves with the situation. My DH of course wanted to go straight to the house and confront him, but she has begged him not to. It breaks my heart to see my once very strong independent dd reduced to a situation where she admits to being constantly sad and finds it increasingly difficult to go to work and have the focus and interest she once had. Also, how can my DH and I act normally around someone who we now know attacks our dd? We have never seen an aggressive side to him, always saw him treat our dd well, and have welcomed him into our family like a son, but now I can’t see how we can continue to do this - we haven’t seen him since she confided in us as he has been working when we have visited. I want to tell him to get out of her life, but she is adamant that’s not what she wants, but as parents, how can we allow her to stay in a situation where she is being attacked and her confidence and self esteem eroded?
