My friend is in a relationship with someone who is lovely but no matter what he does or does not do , she clings onto the relationship . He is bisexual . She is straight. This is relevant because he much prefers sex with men , women not as much . He treats her poorly and she hangs on waiting for any amount of attention . She has a grave history of dysfunction and has never been treated right. A series of twats by his account. He doesn’t boast about how dismissive he is about her wants, needs or feelings but has no shame either . I have lost respect for him. Why do I care so much? . Help me to make sense of it please. I have told him when asked that his treatment seems selfish and a little cruel when all she desires is a serious relationship and has been treated badly all her life from caregivers to friends to men . I struggle to listen to tales of him being the great partner etc. I’m interested but can’t yndwrstand why I care at all? I have no romantic interest in him and he has had lovely partners throughout our friendship but this doesn’t seem to be like him. Frankly I think he is a twat right now. Any advice appreciated about how best to shut him down without being blatantly mean
