Have name changed for this
My dc are adults and dp has 2 young dc who spend EOW with us. I get on well with them and they are not the issue here.
Dp, in my eyes, is a really lazy parent. The kids have set bedtimes but he never enforces them - because they've realised they can take the piss they do. So for example, he will say you can watch one more episode of what you're watching but he won't check back and they will watch 3. Dp does not wake up at night for anything so on the weekend, let's them stay up as late as they want. Last night his 9 yr old was up till half past midnight. Problem is I am a really light sleeper so I can't get to sleep while they are still wandering around whereas it doesn't impact dp one bit as he just gets into bed and that's that. He's asleep now while I'm awake and so are both of his dc. I have a dog that will be up at 630am no matter what so it's not like I will even get a lie in to compensate.
I can live with this for EOW but exw sent a message to both me and dp to say her shifts are changing in the new year and she wants us to have them 4 days a week (Thursday to Sunday) every week. Dp, without even discussing it with me, wrote back to say yes. I said to him don't you think we should discuss this and he said why, I'm never going to say no to seeing my kids.
He's right, absolutely they must be his priority but I don't think I can manage his dc with his lax parenting for that long a period. The above are just examples, there are loads of other things.
Separately his exw has messaged me directly to say she wants confirmation from me that I'm ok with it (I think the reason for this is because dp lives in my house). I am yet to reply to her.
I've been trying to speak to dp but we've had his kids all week this week so it's quite hard to get a chance. I don't think I can do this - am I being unfair? I don't think I am but I'm starting to lose perspective!
