Wow! Ok, first, does he not know most men lose weight easily and most women do not? My mom jokingly complained that whenever she dieter, my dad lost weight. You work on your healthy lifestyle at your pace. Talk to a nutritionist if you can. You may have a food that you think is healthy but is sabotaging your weight loss goals... that's assuming YOU want to lose weight, not him.

Your bf has been ignoring you and wants to have sex with others. He is no longer your bf, he is now your ex-bf and current roommate. Find a new roommate, as your current one is toxic. He doesn't want sex with you, doesn't want to be celibate alongside you, just wants to bang others and have you smile? That is intentional cheating. Move out ASAP
