Confidence issues

My boyfriend has been really off lately and today I finally came out and asked him if there was someone else and he said

No so finally I came out and asked him well what’s the problem and I though out there well what are you just not attracted to me anymore and he ignored it finally he came out and said “you don’t look the way you looked when I first met you, your just letting yourself go” I’ll admit that yes I let myself go a little but I also suffer from depression so I don’t have confidence also.. I have no one to push me to go workout an he doesn’t push me he’s not supportive. I’m so heart broken and hurt I don’t even kno if I want to be with him anymore.. I guess maybe I am fat and disgusting
