Boy, where to begin. You need to really talk this out with her. Women have many needs and you need to recognize them if you are to survive in a relationship. You also need to express how you feel about your training and supplementation without belittling her. More along the line of " really value your imput and concern, it shows you love me but this is also very important me" And then expain to her your views. Even though she may disagree on some of the points never say she is wrong. Just tell her I understand where you are coming from, answer her concerns and continue. By doing this you show her respect for her opinion and feelings and have a greater chance of making your point which inturn she should also understand your opinions and feelings on the matter. Do not and I repeat do not let an argument ensue or you are doomed.
