If your ex is asking for 50/50 custody, it may be because they feel that they are equally capable of caring for the child and want to have an equal role in their upbringing. It could also be because they want to ensure that the child has a strong relationship with both parents. Whatever the reason, it's important to remember that what's best for the child should always be the priority. If you're able to come to an agreement that allows both parents to play an active role in the child's life, then that would be ideal. However, if there is any conflict or disagreement between the parents, it's important to try and resolve those issues so that the child isn't caught in the middle.
