My 24 year old adult daughter lives with a controlling boyfriend, who she has been in a relationship with for nine years. I do not think he physically abuses her but tells a lot of stories which aren't true, possibly to confuse, lies, gaslights, is unreliable and picks a lot of faults with our family. It also feels that he is undertaking a campaign to isolate her from us. I feel exhausted with endless drama. We had agreed to give my daughter a contribution to a house deposit, and she is now looking a property to buy. I do not think she should purchase with him for many reasons, but that is currently her plan. Do you think I should change my mind about giving the deposit or will this further damage relations with my daughter?
