My partner has started going to the gym he says hes going to better himself. He started going at 4am but now he’s just going later rather than stick to his normal time. Hes distant from me and argues with me a lot. Hes giving me the silent treatment. Surely it’s not normal to wear cologne he doesn’t come back with a sweat either. If I confront him he turns around and says it’s all in my head. Hes cheated in the past but not on me. What do I do?
