That still does not explain why no contact for 10 years. And how it was your choice to not make contact. And even now it seems your ex wife is the one pressuring you to meet the kid simply because you have a new wife now.
Yes I would say it is a good idea for you to meet the kid. But it should have been done much sooner. Just remember you have your own life now with your new wife. But only meet the kid if you actually want to meet the kid. Don't meet simply because of pressure.
