Instead of holding your feeling in.....just tell him or her how you REALLY feel!!
My story is different because i'm not married to him. But there were some serious SKID and BM issues that made my stomach turn. I would tiptoe around these issues hoping that things will change, etc. Well tonight I had enough. He has been ignoring me for a few days and I left him a calm VM outlining how pathetic his life, the BM and skids are and how I predicts their future. I was just brutally honest, not vindictive. I felt a huge relief afterwards!!!!
