Let her first see some positive happy marrieds, because the men I know only dated girls who were excited to date them and in the frum world we date for marriage (opposed to the secular, just friends, casual dating).
Have her talk it out, visit stable families, see real caring, loving and secure couples.
I would say wait it out with a month of working out her issues and then let her date she might end up really liking a guy–but she has to know to date for marriage!
I guess I’m trying to protect the guys because they might like her (which is very likely) and she wont commit!
