I thought it could be because he worked out every single day, or the stress of his job, or the
vitamins he was taking. He said I could be right. In the end, I did hear that he cheated on me. So I now think it was either guilt or he wasn't focused on me.
Now, I am with someone new. And again, he is very physically fit, and works out every single day. He has a lot of work stress also. He also takes a lot of vitamins and antioxidants.
