How should a man deal with the fact that the woman he loves has been diagnosed with breast cancer? She's devastated. So are you.
She admits it, acts like it. If you’re a typical man, you don't admit you're devastated (perhaps even to yourself), and you focus on being a tough, tower of strength. You support the woman you love and don't show, or worry about your feelings. This is how guys are supposed to act, right?
If you really want to support the woman you love through her diagnosis and treatment for breast cancer, you owe it to her and you owe it to yourself to make sure you’re fit, well, and mentally prepared for the task ahead. Spending time on this website is a good place to start.
