Why would you date a guy who is telling you that you are gaining weight and that it is not looking good. That's absolutely horrible and will not help with your recovery. That statement upset me the most because that has happened to me in plenty of relationships and I had to "man up" and breakup with him because he was putting to much stress on my eating behaviors. Maybe this is why you are binging in the first place. Stressed trying to please his idea of what a good body image is. There is no sure fire way to stop binging but you can find the reasons that cause you to binge and lower those so you binge less often. Best of luck!
