No, you know she's not realistic, well probably not since one can never predict 100% what court may decide. It surely won't grant her what she wants but it might allow her to get majority time - and you relegated to alternate weekends - since that is more likely with teen children. The sooner you get a return to the prior pattern, the better.
Essentially it's a bluff, entitlement too, sort of a
Hail Mary since you opened the door by weakening your previous Boundary of equal time. Another lesson we learn the hard way that consideration and kindness aren't reciprocated when dealing with BPD traits.
The fact that summer break is here may not necessarily be a deciding factor for mother's benefit. I recall that when I moved up from equal time to majority time, thank school teachers willing to testify, I got what I sought but for whatever reason the magistrate left summer at equal time.
Be aware that the sooner you file to get the prior schedule reinstated, the better. It can be a month or more for many courts to start hearings in response to petitions and motions. And beware that your stbEx may try to get continuances to later dates to delay action even more. Hopefully, with legal action pending, she may relent and agree to return to equal time sooner.
A word about temp orders... My impression - my experience too - is that courts and lawyers are quite reluctant to modify them unless absolutely necessary. (After all,
supposedly they're only "temporary".) I had multiple reasons to contest my temp order but it lasted relatively unscathed for two entire years until the final decree.
Does your temp order or the court's policies allow vacations during temp orders? Don't think you can't take a week or two off with the kids to take a vacation, just avoid planning a vacation on a mother's holiday time. (In your case, nothing too vigorous for the teens' recovery.) Likely the temp order itself may not mention those details but likely your local court does have a structured guideline posted on its website that does. Mine lists several categories.
- possible schedules for very young children, school age children and older teens
- alternating every possible holiday or child's birthday event (strike out whatever does not apply)
- time away (vacation) 2 or 3 weeks per calendar year with a maximum of 1 or 2 weeks at a time
Lastly, older teens, especially ones who can drive, are sometimes know to "vote with their feet".
