OP, I get it, I really do. It can be relentlessly exhausting to have to continually parent without any real downtime.
how is your dc’s relationship
with their dad? Are they organising things on ‘his’ time because they aren’t really bothered about seeing him?
is it possible for you and exH to be a bit more fluid with weekends - eg check by Wednesday what the plans are and then decide where the dc will be? Not ideal for long term plans, obviously, but possibly a way to ensure some downtime?
only you know, or can take a guess at, the situation with your dc. Maybe they aren’t that bothered seeing their dad, or are trying to lessen the time spent there. Maybe they are just being unthinking teens, expecting a parent to drop everything and Tina round after them (why aren’t they expecting this if their dad?)
posters here can only put their spin on it. To me, I fall on the side of posters who are saying this is what happens when you are a parent, and you need to dig deep and be there for your dc.
I am not a martyr to my dc, but I have not had any significant time without any of my dc in the 5 years since exH and I split. In my case, it is complicated by SN, and also by exH and the dc not having the best relationship (his fault). Eldest has had phases of going to his, then not at all for a while, then back to his. Middle one has not seen him at all (at his house, they will come along on eg family birthday occasions or similar) for well over a year now, and has little intention of going back for EOW. Even the youngest has had periods of not being able to stay at exH’a house. In my case, if I set out to my middle child that I really need the break and she needs to go to exH, it would put more pressure on a child who is already going through a lot. She doesn’t need to feel unwanted here, or that she is making my life harder etc. it is hard enough for her that she has got to the point where (initially as a young teen, but still as a mid teen now) she has had to deal with stuff that has made her go virtually NC with her dad. I can put more on her and just say ‘well, it’s his time, off you go’.
and that’s what I mean by only you being able to tell/feel what is right in your situation. I could have easily just said ‘YABU, you’re a parent, step up’, speaking from an experience where I have had to step up, but only you know/can begin to tease out whether your dc are trying to avoid/cut down time with their dad, or whether they aren’t really thinking it through.
you mentioned you are worried about the impact on their relationship with dad. I’d start by having a discussion with the em about this, and suggesting they can only ‘opt out’ of one weekend with dad each month, as you don’t want that relationship falling away. They may surprise you with their responses (eg my middle dc, when I had this chat with her as a 12 year old originally) told me she didn’t have much o a relationship with him anyway, spent practically all of her time at his house just sitting in her room to avoid what was going on elsewhere, and that she wouldn’t be missing out on anything anyway.
