Dude, What are you thinking???
She probably looks just fine. maybe just a little toning?
I was up to 190 punds at 5'4". I came down to 140 and I looked great! Now I'm 125. I was down to 116 at my lowest. How little do you want her top weigh?? I was 132 at one point when I was working out alot and I looked fabulous. You should calm down a bit and apprecite your girlfriend for who she really is. From what I hear, most men like curvy women. Guess I was wrong, huh?

Now, on the other hand i know how you feel because i lost nearly 70 pounds and my husband has put on alot of weight. at one point he had asked me if I was too comfortable in our marriage that I didn't care about my appearance anymore.
By the way, I'm bipolar and on alot of weight gaining meds.
He has gotten quite large to me. I do not say a word to him. I do not want to hurt his feelings. He's still good looking. But recently i've been noticing how over weight he's become, so i know where you're coming from.
I do not think of other men though. i just am not as turned on as I used to be by him.
