My opinion about your wife and your marriage didn’t change since your previous posts. It’s very unhealthy for your child to be witnessing this dynamic.

Now in addition to all other nonsense your wife subjects this family to she’s teaching her child that silent treatment and locked doors is the proper way to conduct relationships.

When childless people engage in abusive or otherwise unhealthy dynamics it’s their right to live this way. But if one has children, they need to be mindful of what they teach their kids. Your kid is creating a foundation for her own unhealthy relations patterns when she grows up. How sad.

If you do decide to leave, please collect enough data so you have the custody.
