I was only semi-serious with my remark.
So the girl in the picture looks great according to your post. I tell you your gf looks nothing like her and your response is "thats why im with my girl"? LoL. That sounds like your are with your girl even though shes not looking great.
Nah, i wouldnt.
What i mean is: I find it weird when i see someone "admiring", lets say, model-type looking girls, knowing that the guy has an overweight girlfriend (she doesnt necessarily have to be fat. Its just that there are worlds between the women he finds attractive and the woman who is lying next to him in bed at home).
This concept doesnt fit to you and your girl though.
