Ok so I will try and keep this brief! My friend split up with her husband last year and confided in me that she no longer wanted to be married to him after 20 odd years and that it was her decision. She told me there was no one else involved but suspected he had a girlfriend after she told him it was over. She made a big deal out of this and played the victim as in ‘how can he move on so quickly’. I felt for her. Turns out now she has a boyf. This has progressed quickly according to her timeline from when they ‘met’. I have since found out that other friends (& now I) suspected this had been going on before her marriage ended. Since publicly splitting from her husband she has thrown herself into this relationship having zero time for any of her friends, taking days to reply to messages, being too busy to meet up etc. any interactions with her are full of falseness and she confides nothing in me anymore. A group of us go on a diving holiday every year including her - she only knows these people through me - is it awful if I suggest they don’t ask her to go? And how do I do that without her knowing I have had enough of her lies? I don’t want a confrontation as I have to see her a couple of times a month through work. Am i overreacting and should I just suck it up and be as false as her for the holiday? Or not go myself?
