ocho cinco- a lot of your post is responding to what Yserbius123 said, not me. Please specify who you’re responding to.
In case you didn’t know, I’m a girl.
Obviously singing is not vital to the foundation of a marriage. As someone who loves to sing, I can understand where those who make it a ???? in a shidduch are coming from- but I disagree with them. When I met shadchanim, I used to say it as an aside that it would be a nice bonus if the boy could sing, but not at all a ????. My chosson doesn’t sing, and to be quite honest, it doesn’t bother me. As you said, there are other, much more important things that form the foundation of our relationship.
Look, I’m not a boy, so I wasn’t really trying to give you advice. I know that when a girl is not so attracted to a boy, they will tell her to try to focus on one feature of the boy that she likes, and see if attraction grows from there. From what I understand, boys tend to be more holistic when judging looks.
One thing I do believe is that if it is the right one, attraction will grow, regardless of whether or not the person is objectively attractive. You just don’t want to throw away an opportunity at a shidduch because you are not instantly attracted to the girl. When you like a person, their looks tend to grow on you.
