Oh dear, reading this really made my heart go out to you, what you went through in those early weeks postpartum was genuinely cruel, and the fact that you've recovered so well and your baby is thriving after leaving says a lot about how much strength you have. The part about him threatening to separate you from your newborn is something you should not take lightly, in Singapore, for a child this young, courts generally lean heavily toward the mother's care arrangements especially during infancy, so please speak to a lawyer sooner rather than later to understand your position before he tries to set any narrative. My friend went through a rough postpartum separation and she said the Legal Aid Bureau was a good starting point if cost is a concern, and her lawyer was very clear that a mother leaving a difficult home environment is very different from abandonment in the eyes of the law. It is also worth noting that divorce does not automatically mean losing your child, some parents who separated actually found they could co-parent more peacefully than when they were together under one roof, and the child's stability matters most to any judge. Weigh it carefully, but do not let his threats paralyse you, you are clearly doing the right things for yourself and your daughter already.
