He's lost his looks.

Too funny! Yes, anybody who is blessed to be in a long term relationship or marriage, hopefully understands their significant other will have physical changes. If one is only attracted to the physical attributes of a person, then your relationship is doomed. I try not to judge because all of us will grow old (if we are lucky), and slowly become invisible to most people. So in the grand scheme of things, you are definitely "up sh!t creek" if baldness is a deal breaker.

I'm sure he wouldn't find you attractive either so don't feel bad about not being into him anymore

... and who says women can't be just as shallow as men?

He hasn't lost his resemblance to Liam Neeson, that's for sure.

Happens to the best of us. At his age you'll probably be twice as hideous.

Take a mirror check when you're sixty and note how well you're holding up, compared to when you were in your thirties.

It is definitely the hair. I mean he wouldn't look exactly the way he did when he was younger if he had a full head of hair now. But he'd be damn fucking fine. Look at Kevin Costner and Don Johnson. Still fine as fuck now with full heads of hair. Whether it's real hair or not real hair that's beside the point. But still, hair does make a big difference.
