My girlfriend wants to lose weight but she's thick in all the right places i don't approve of this?

Her body is right! In every single way. You know what they say once you go black you never go back! She's got a small waist but a huge a**. I can't even explain it, cause I wouldn't be doing it any justice... you just have to see it and she's got a nice pair of **** on her. Lately she's been hitting the gym on the regular even more than me and she's been cooking healthy food. Ever heard of vegetarian meat? Yeah me neither. Why? Why? Why? I love her regardless don't get me wrong but I love her the way she is. There's a difference between fat and thick. This morning she woke me up at 5 :30 talking about how she wants to know if I could go jogging with her. The f*ck? She's taking this too far. One of the reasons why I was attracted to her before I even got to know her was because her body was ridiculous and it still is and now she's getting all biggest loser on me. Her not losing weight will do our relationship a favor! I'm attracted to what I'm attracted to and if I'm not attracted to her anymore then I'll find someone else. If anything she should do it for the kids. I love her just the way she is. Obviously I don't just love her body cause I had 3 kids with her but I'm just saying...she's not the only one out there with a nice body..do what you gotta do to keep your man right?!
