I'm going to make my girlfriend insecure about her body
Does she have a serious problem?
No, she just has a little fat around her waist, that's all
Trying to make your partner feel bad about their body is very rudy and abusive. If anything, you should be supportive and kind to them, that's why you are in the relationship in the first place. Instead of mocking her, which might break up the relationship, you should think about showing her how much she means to you.
I'm trying to make sure my girlfriend be average. Guys like me are above average and girls like her are below average. Life sucks so let's see how she feels when she's with guys who are below average.
It is wrong to hurt her feelings because you feel a certain way. it is really rude to disparage her body and how she looks, you should break up if you are unhappy.
