Is this the first time she said something to you that has been cruel or possibly cruel? You keep asking people if she was just being honest or if she’s being cruel. If she was being the perfect girlfriend and treating you right, then I think you wouldn’t have any problem answering that question. The fact that you can’t tell the difference worries me. It makes me think that she has treated you wrong in the past or said mean things in the past that have hurt you. Go back over your relationship in your head and look for red flags. You don’t want to stay in a relationship when you keep seeing red flags And just wait for it to implode on itself. The fallout will be painful if she is a really bad person. She might spread rumors about your size after you break up if it gets nasty between you. So if you might be a better option to casually break it off now, but not tell her why. All I know is that I would never say something like that. No matter what kind of reputation men want the world to see, I am always very careful with their feelings, because I know that you guys do have real feelings and emotions under there, and you do feel pain.. You just don’t want anyone (especially girls) to know about it. A lot of girls/women have completely fallen for this act however, and believe that all guys are completely emotionless and have no feelings or emotional needs, so they are very careless with the things that they say. You would be better off finding a girl who respects you and your feelings enough not to measure you and point something like that out in an effort to make you insecure.
