it depends what else she knows about him from seeing him around the community. It could be that she was seen things about him midos wise that she would not find compatible. It could be that she knows the family and there is some red flag to her. Just what she answers a shadchan is not nessecarily the whole picture although in profile it might be what she is looking for.
I personally think its unacceptable to suggest someone go for counseling unless you know her a lot better than you made it sound.
