Visitation ?

[texastracy]

ex has brought petition to modify visitation from every other weekend year round and 1-2 nights during the week during summers months down to 1 day (sat-sun) per month citing that the kids are busy and have numerous social obligations.   At first, the children told law guardian they want the 2 weekends with the second being flexible and they can pick when they come.  We agreed.  Now, the children have changed their position that they only want the 1 day per month.   All parties believe the ex aided in their changed position but it is what it is.  The children are 13 and 14.  Father has never not gotten his children since the parties first separated in 1995.   Is the children's new position enough for a judge to reduce the visitation?  Father has been flexible all these years in allowing the children to attend activities on his weekend and working his visitation around such events.  Help ! This doesnt seem right.
