My sister lives abroad and my BIL passed away some years ago. My niece (sisters daughter) is 26, she has a 11 month old daughter - no concerns or issues there at all. Dad is not on the scene . She told me she has met someone - she seems really into him and has been seeing him for a few months Some of the things she’s told me he has said to her are in my view- well quite mortifying and show a total lack of respect Examples- “I’ve told my friends I’m shagging the arse off of an unmarried mother”, “where would you be if you hadn’t met me ? “ .She told me that when she told him not to speak to her like whatever - he replied that he’d talk to her how he liked. She tells me that he’s very good with her daughter . He sounds like an utter twat to me but, I appreciate there’s not much I can do - other than to monitor and hope she dumps him. But any advice would be greatly welcomed.
