Child won't sleep in own room

[Anon092727]

Little back story my son hasn't been the best sleeper but eventually got him sleeping in his own bed with one or two wake ups by the age of 2,
We moved house about 5 months ago and he now wakes multiple times a night wanting my bed, screaming mums bed which I always give in as it gets hard sitting by his bed for 30 mins he wakes , wakes every hour unless in my bed,
I've tired everything I can think of his bedtime routine has been the same since he was a baby and doesn't nap anymore.
The issue is he only does this at home with me, he goes to his dads two nights a week and sleeps perfectly fine in his own bed and doesn't wake at night, or when he has a night over with my dad once every few months
He's now closer to 3 and im exhausted and lost what to try at bedtime and wouldn't mind my own space back at nights.
Any advice would be helpful

Also when my partner stays over he will still wake but won't ask for my bed and will settle back down in own bed

I understand why he ends up in your bed as it's exhausting having hourly wake ups/sitting by bed. I think you need to give it a few nights of awful nights though, so he understands that going into your bed is no longer an option. Saying this from experience as with my DC1 if there's ever been a night when DC1s come into my bed, then we've had a run of night waking/wanting my bed following that which only ends after a couple of nights (or at worst 3-4 nights) of multiple, long wake ups when I'm sat next to DC1's bed.
