Do me a favor: Do your trauma work!
We often underestimate the depth of childhood trauma in individuals we choose for a partner; if we treat them with love, grant them safety, and court them right, we can somehow live happily ever after. We forget that their childhood, with its complex and deep-rooted traumas, is the biggest roadblock to having a healthy relationship. Just hear me out here. Suppose you grant your partner, who grew up in a chaotic household, love and stability. In that case, they will reject it and subconsciously sabotage your love and stable relationship for the chaotic familiarity from their childhood. Love and stability are foreign concepts to their subconscious mind. If their caregivers treated them with hostility, criticism, and cruelty, that is what "feels right" to them when they seek a potential partner. They would want a partner that embodies the same behavior towards them in their adult relationship. In other words, a red flag does not feel like a red flag when it feels like home.
