The term “opposites attract” can be biblical or unbiblical depending on what you mean when you say it.
In fear of hurting a woman, sometimes a man will just move on from her rather than telling her what the specific reason is. There are things men really want their future wife to have, but they are not going to try to help a woman have those traits. Rather, they are just going to look for a woman who already does have those traits and move on from the women who don’t.
