Relationships

I am highly intelligent. But I’m pretty sure my fiancé thinks I’m a lazy idiot. I constantly forget to do things, simple things, he’s asked of me. He thinks I’m lazy because of my struggles with keeping up with housework. And thinks I just don’t care about paying bills or opening my mail. I have been diagnosed and am on medication, which helps, but he still doesn’t want to accept or try and understand. How do ya’ll work with your significant other on this issue?
