My boyfriend wants to go on a diet

My boyfriend and I been dating for little over a year now, and I am a bbw. I'm a bit over 420 pounds, and he has always made me feel like a supermodel. He would always say i was the most beautiful, he would always look me in my eyes and kiss me. It was like i was the only person on this earth. <br><br>Last night he opened up to me. He says he wants to live a healthier life, lose weight, eat better, and exercise more. He says he has never done this before and wants me to join him, so we can do it together. I have never told him this but every time he says how beautiful i am i feel self conscious. He has never made me feel anything except beautiful. But this made me feel guilty. I felt like i was the reason he needed to do this. He never said this was my fault, but i felt like it was my fault he needs to do this. I felt like i was the reason he was overweight and he felt he needed to do this.<br><br>So i told him yes, and we started last night. I made us a healthy dinner, and we both ate well. Today, we worked on making our lunch, and we went for little walks. I even took a flight of stairs down and felt so proud. I never thought i could do it. <br><br>I do feel a bit guilty doing this, i do love my body, but i don't want to leave it that way that he feels like its all because of me. I just want us to be able to go out together, and do things together. I want to be able to do things with him, and not have to worry about it.
