So you are saying that if you guys go out, and you are with your "friends", they will make fun of her for her looks? It's one thing if your friends talk to you personally about it behind closed doors, it's another if they say it to her face. That's just disrespect out of arrogance. Also, are you sure your friends would do that? Has this happened before, where you have gone out with someone, and they have made fun of her? If they really are like that, as other folks have said, you are probably similar to them, so don't hurt her and put her through the misery. Some women tend to take other's perceptions of them to extremes, so it would be best mentally for her to not have you!
