Keep your distance from women with low self-esteem. Most of the times fence sitters are waiting to stab you in the back after several years of marriage. If she values the opinion of her friends over what's objectively right for the both of you, consider this a massive red flag and don't bother engaging with her anymore. Insecure people are prone to demon possession, and there is no one in this world who can help them but themselves. The most compassionate move you can make is leaving them alone to avoid drama and traumas.
