How stupid will I look if I call him again?

I just laid it on the line with a guy who only wants to be my FWB. He has stressed this with me and was embarred to be around me with his friends, positively, and I have my ideas why. I told him I don't want to be his friend or FWB and that is because he was ashamed of me. I told him that but I didn't call him names. How stupid will I look if I tell him in a few weeks that I miss his friendship and that I'm fine w/being a FWB? Any tips on how to recover my ending our FWB'ship? Thanks!
