No, not when your distance is about punishment for a perceived injustice. Detaching, and going dark is about distancing yourself for self protection. To allow the other to follow his path, but not drag you along behind. To allow yourself time to heal.
If I understood you correctly, you have used silence in the past as a 'weapon' of sorts. This is different. This is saying, "These are my boundaries. You have chosen a path I cannot follow, therefore, our lives intersect ONLY where there is no avoidance - our child." No family dinners, rides in the country, texting. Your H has chosen to leave you and your son behind. That means he has to understand the prospect of exactly what he has given up. His son will always be his son, but will you always be the family he can run to when he is feeling paternal and homey? I hope not, for both you and your son's sake.
