Sounds like you found a good friend

Casadena

I am a 60-year-old man who recently met a lovely woman my age. She is smart, funny, attractive and independent. She is also borderline anorexic and barely weighs 100 pounds with emaciated arms and a protruding breast bone. She basically eats protein bars and works out several times a day. She has bragged about her six-pack stomach on numerous occasions. I really like her and her company but her physicality reminds me of a child and is hampering my desire to be intimate. What do you suggest?

What an unbelievable jerk.  I'm so sorry her eating disorder is getting in the way of you getting it up.

I'm guessing this started as mutual romantic interest.  But if he's not attracted to her, this won't work and he shouldn't deepen the relationship by having sex with her anyway.

I'm also translating "Her physicality reminds me of a child"=Her boobs aren't big enough for me.  Because thin women, especially past a certain age, don't have childlike bodies.  

He needs to break up with her and offer friendship.  With a general statement like "(insert reasons he likes her company) but sees her more as a friend."  There's a good chance she won't be interested in that, but then that's the way the cookie crumbles.

But this letter reads like he's looking for permission to complain about her body, in the hopes she'll change her eating and exercise habits to be more physically pleasing to him.

She possibly should change her eating habits for her own health, but that isn't his business.  She doesn't think that and isn't going to listen to him anyway.
