Leave them or split them?

Hiya!
Just need some advice, i have taken on a rescue rabbit, which i got last wednesday..
I have another rabbit and seperated them until the new bun got used to his new home. Hes been neutered.
I have tried them together for the last few days and seem very happy together, they have had a chase and jumped on each other which it seems is natural, have given each other washes and there seems no aggression. I think my older bun thinks its her mate back (he died last year) as hes identical to her mate..
Now i dont know whether to split them again at bed time or just leave them together now, they are outside in the hutch/run together and have been for the last few hours.. and do seem quite happy?
should i leave them or split them for a while at night?
thanks again for help once again!!
:wave:

Do you mean split the ones you have bonded? If so I would leave them if they have been getting along fine.

Unless there's a problem, leave um together

I'd definitely leave them together. If there was a problem you'd know about it by now! Be pleased by a successful bonding

They are still together running about and had their tea together.didn't know if splitting them until they have been together longer was best thing to do
