Studies have recently shown that some children respond best to joint custody as opposed to sole custody, where only one parent has primary custody of the child and sees them much more often than the other. The enrichment that is provided by having two parents isn't dampened just because you and your ex-spouse are no longer married and don't live together anymore. The benefits your child could gain are very real.
It's tempting in many cases for people to want to go the aggressive route during a divorce, especially if they feel hurt by their ex-spouse. However, collaboration and mediation are great ways to ensure that the divorce proceeds as smoothly as possible for everyone. Neutral third parties are able to calmly assess your situation and decide what's fair for all people involved. They can also help you create a parenting plan that will provide your child with the care and time that they need to see from both parents to thrive.
There are other, more aggressive divorce options out there. However, collaborative law might be a good place to start if you believe that things can be talked out.
