Hello,
Long story short(ish); I have worked around my USTBxW’s work shifts since April 1st this year (since uncovering her infidelity)- we share D4 & D 10 50/50 and she has managed to alienate S16 from me. At that point she reduced her working hours by 25% as a nurse and subsequently went onto permanent nightshift 3 (varying) times a week. She said this was so that she could still look after the children so a late shift backing into an early wouldn’t mean she saw them less as we now live in different houses. Sometimes I haven’t received the next batch of shifts until 5 days before they are supposedly known which makes life very difficult for me to plan.
Once the shifts are made known to me, I append them to an online calendar (determining 4 nights and 3 nights for each of us=50/50) and she was supposed to check them for errors/hand overtimes etc. She stopped checking this in mid-Oct when she withheld our daughters from me without any reason or justification. Further to my L getting involved, she then restarted the mediation process at which time she confirmed there was no adequate reason to withhold the children; mediator acknowledged it as one of many “one-offs”said USTBxW’is now too busy to confirm the details on the online calendar, but agreed that by not letting me know of any issues within 48 hours, the default position would be that everything is fine.
Now; I have made her aware since April of only 3 instances where I would not be available, one of these being 29th Nov. She is adamant that as she has not taken the liberty of requesting that night off to look after the children; that I must have them regardless of the fact that I have already noted that I had another engagement (the fact that it was a concert in which I have also given a ticket to S16 to attend (six months ago) seems immaterial).
In short, I can't keep going on this way and wondered how other people resolve to work around the shifts and subsequent entitlement that becomes apparent; I have disengaged, merely stating repeatedly that she has had 6 months notice and I cannot be held accountable for the things she has failed to organise. (Granted I could organise a babysitter, but she would then not be working around any of my availability and me constantly around hers which isn't a good precedent as she had managed to book off the 1st Nov to get drunk with a friend and only saw the kids 2 nights that week as I had them for 4 and their grandparents the other one, yet she is explaining she cannot only see them for 2 nights next week(ludicrous ) - anyone else in a similar situation - any tips?
