Background: my boyfriend and I have been together for 2 years, having been friends for some time before that. We have a large age difference but have an incredible bond and are best friends. He has been separated from his wife for 4 years but they still live in the same house (they don't have sex). I live in London and she lives in Italy - he commutes, spending the week with me in the UK and the weekends with his children.
She has had multiple affairs openly and manipulates him unbearably (she has threatened to stop him seeing his children). He financially supports her (as well as her sister and brother). I find her behaviour disgusting, she only speaks to him when she wants money or a new car and refuses to do anything for him or the household (she is a sahm) - including disciplining the children, cooking, cleaning or food shopping. He does all these when he gets back after a week working in the UK. I try hard not to constantly be horrible about her, but it is hard to see the man I love being taken advantage of so viciously. I know they are not going to divorce (for the sake of their children) but I really can't see how this is a good alternative. He admits that she is awful and has got very angry about some of the things she has done (notably bringing her boyfriend to their family home to spend the night when his children were there), but he is incapable of doing anything about it and has aided her boyfriend's business and bought her property. Am I being unreasonable to expect him to tell her about me, stand up for himself and stop being a coward as well as getting divorce proceedings under way?
