I fought for joint residency NO SUPPORT from day 1. We spent hours in mediation where she would preach about wanting our daughter to sleep at her place M-F during the school week. She wanted that "stability" for her. Usual WAS mentality that it's all about them. I would then reply with I agree. She can stay at my place m-f and to my amazement the mediator agreed and told her the same. Then she tried scaring me by filing a petition for full. Which led to the court assigning a GAL (Guardian ad litem) and having the GAL report state that I should be giving full custody. Only then did she start seeing my perspective. Has been great ever since.
We eventually settled on a joint residency co-parenting arrangement where I would have her Wed/Thur and every other wkend and she has her mon/tues. and every other wkend.
So decide what YOU want and dont back down. You and your kids will regret it later.
Hold the line. PMA
If there is such a thing as a great story when a D can't be avoided, this is it!
