I wanted ... .sole legal custody but I altered my demand (sole custody) before my mediation because my L said it will not happen so I did not bring to the table.
Gaining sole legal custody is not common. Courts don't want a parent to feel locked out of being a parent. Generally sole custody is granted only for substantive child abuse, endangerment or neglect. Don't feel it's all a lost cause. You have the right goal but not quite the right tool. Consider seeking ":)ecision Making" or "Tie Breaker" status. It still leave you two with joint legal status but it means he can't obstruct you for months and $$$ while you wait and wait to get your objective done with a mediator or a court case.
* These are essentially almost like sole custody but allow the other parent to still say it is joint custody, language the courts like to maintain:
DM - Decision Making -- You have final decision, proceed and notify Ex of your decision.
TM - Tie Breaker -- You seek agreement from Ex on major decisions first but you have final decision, proceed and notify Ex of your decision.
He is really moving with his fourth GF and he wants to be a before care--me dropping the kids off at 6:15 am then he will feed them breakfast and give them a ride to school (8:35 am) and nobody has to pay before care.
This may save some $$$ -
sounds to me like his real goal is to minimize his child support obligations - but is it worth it? As you wrote elsewhere in your post, "how long will it last?" That's why I put in my post above that the order needs to be clear, difficult to reinterpret to his favor and close as many loopholes and gotchas as possible. Then, since you are the agreeable sort of person that you are, once you have an order that works for you and the children, then from that secure position you can allow
some additional time as appropriate. You can always say, "This is what is working and will work now. Maybe later after a year or so we can reconsider the schedule. Meanwhile I can always consider occasional requests."
The point is that you can reciprocate his good behavior - no problem at all - but it is unlikely he will consistently reciprocate your good efforts. Don't lock yourself into an order which presumes you both reciprocate but you know somehow someway he won't. Yes, some things you'll have little choice but to settle or have the court decide, but don't go there willingly, not if you have good reason to believe it isn't right or won't work.
Before I asked him once why he does not come to kids graduations, conferences, etc. He said because it is emotionally too hard for him (he cried) now all of a sudden he shows up at school with his GF, and said he signed up PTA and volunteers. I don't know if it is true and wonder how long it will last.
See why trying to reason or whatever with the Ex just complicates things? As my lawyer always said, his #1 priority was to sit on his clients to shut them up and stop them from making his case that much harder to resolve. As you found out, trying to reason with him did get a response but (1) it made things more complicated and problematic for you and the children and (2) his changes probably won't last.
