Cannot say if he has good intentions, but calling you fat or stupid is mean. A partner should support you and not bring you down. He might be having a hard time himself for whatever reasons (providing financially for his family comes to mind), but it is immature for him to dump his negative emotions on you. It is not for us to secide if these actions constitute emotional abuse, since we have only heard your side and we do not know either of you but there are nicer ways to tell someone to get in shape than he did in my opinion. He may be needing support as much as you rigjt now. Did you ask him why he has distanced himself lately? Have you considered couple's therapy? Hope you can work it out and make te best choice for yourself.
