Wowzers
I cannot speak for others and my situation was/is opposite. For me the answer is no. I was heavy 178 pounds to be exact and I am 5'5, 7 years ago i dropped to 109 I am now up to 140, to some that maybe just right, to others I would be overweight???? I guess it depends on who you talk to?? You know what I mean.
Every body that new me in the fat days, says I look really good to stay where I am at.
I even had liposuction 4 years ago thinking it would give me the perfect body...didn't happen, yes it's better, but not what I wanted and I'm still not happy with the way I look in my jeans, shorts, etc.
geez, listen to me! Sorry about that.
Again, I know for me I will always be fat, so your girlfriend will/may feel the same, I honestly don't know.
Hang with her my friend, you sound like you really are concerned and sincere
