I don't know what to do I feel really gutted and sad. I can't see a happy ending to this as my mum hasn't been happy in her marriage for years but won't leave my dad. I don't really want to go into details but just wondering if anyone else had experience of this later in life, I'm 38. I know a lot worse things can happen in life but it's really knocked me for six. I am cynical enough about people being faithful in marriage but really hoped at least my parents might just be loyal.
