My gf and I have been dating over a year. We have been happy until recently where she thinks I am too young and she feels that I don't take her advice about weight loss and that she feels that I want children whereas she doesn't. I have told her that as long as I am with her I don't mind not having children and that I am working on my weight loss (I am not obese but I said I wanted to be fitter to her). We have had a few arguments recently but I feel that the reason for it was the concerns she had. We had a big fight last evening and she left me and blocked me out of every possible contact. I don't know what to do. I am in love with her and i don't want to lose her.
