They sound like they're doing really well together, time does really help them get the hang of each other too
My two were in separate beds until Dave was about 1.5-ish I think, they slept in separate rooms until he was about 8 months as he was such an annoying wotsit as a pup
) but they've been sharing a big bed for about a year and a half now and love snuggling up together - although I think Normy would be just has happy with her own space
but she does like to use Dave as a pillow so it works for both of them
Dave was possessive over toys and food etc but Normy's not bothered - she won't let him take her food but she'll usually give up toys or sticks etc and he ALWAYS has to take everything she has
but it works quite well having one that's not that interested - or happy to give them up as there are never really any spats - so your two should be able to work things out between them brilliantly as time goes on
