I hate to to do this knowing it's really gonna piss some people off but here we go .
Sweetie if u have lost a lot of weight he's probably jealous , I had my bypass in 03 , I lost 175 and my partner of 11 years was so jealous. Why I don't know she was thin herself . In time I gained ALL the weight back and she honestly seemed happy about it . Needless to say our relationship ended after 16 years and I am now in the process of getting it back off . You do what you need to do for you to be healthy and feel good and if he can't support u in that something else is wrong and he's using that as his scapegoat... U keep up the good work my thoughts and PRAYERS are with u ...
