@JPM1006,
In your posting header you call her your soon to be ex-wife and in the body of the posting you imply she is already your ex-wife.
In any case in the divorce your rights to visitation would normally be set up by the courts along with child support and other such matters.
Without any court rulings and you are still married your rights to the child should be the same as hers.
I would suggest seeing a lawyer no matter how you do it. and some lawyers will give you some free time at a first meeting.
