I'm not attracted to him anymore?

So I've been dating this guy and we met online and it became very intense quite quickly. When I first met him I wasn't attracted to him but he wasn't unattractive so I thought as I really liked him as a person I'll ignore it and give it ago and hope attraction grows with connection. Over the years we've both been through rough patches but during this period he's gained 5 stone and I feel awful saying this but his body makes me feel ill. He has tried to lose weight but he's always been overweight so it never feels enough. I love him because of who he is and its making me extremely depressed because I just don't see it working long term. I'm so attached and emotional invested in him, I just don't know what to do. Should I just ignore it?
