she needs to work on her self-esteem. Weight is not that big of an issue for men as it is for women and they are the ones that are too hard on themselves.

Op is insecure and she needs to deal with that first and it should be ok in her mind to be overweight and ofcourse it matters for her if she is coming and asking a question here.

some of those BBWs are confident in themselves and also love pleasing their men and don't complain about weight. It is important since no men or women like to hear complaints all the time.

Many men are into BBW's and only BBW's. You should focus on finding men who like you as you are.

she needs to lose significant weight and take care of her health and life before jumping back in dating.

Looks like OP had a very good catch with her ex-bf and not sure exactly what happened but it could be that her own insecurity about her weight and self esteem that was causing issues in the relationship. After break-up, she is on the bandwagon for dating again rather than working on herself, losing weight etc.
