If I had money, I would get it. Cosmetic surgery is fine in my opinion. Also, a woman's comfort level with her weight is more about how she sees herself, it's not something caused by your lack of loving her enough. So don't feel like you've somehow caused it. In my personal opinion, the most supportive thing would be to tell her that you love her the way she is but that you support her decision either way I had my breasts augmentated and that's what my partner told me.

It may make her feel good. Our daughter is finishing residency as plastic surgeon and she tells us stories of how small alterations can bring some people such comfort and personal confidence. One woman was working out and dieting till she was rail skinny, but still had "under arm wings". Flaps that embarrassed her, and really effected her life. She didn't want to go out, get dressed up...etc. A little nip and tuck trim and this woman is like a new person. Her husband wrote my daughter and her "chief" a glowing letter of thanks for his new, "confident" wife (he never saw the physical issue...SHE did). Later his wife wrote them a wonderful letter of thanks as well. If your GF really wants this lipo, it should be because she wants it. If she wants it that bad, then your job is to be supportive of her choice. It is, of course, her body and her choice.

Absolutely if I could afford it.

Absolutely not. I'd much rather work out and diet rather than pay so much money.
