Hello and welcome from me, I think canary has summed it all up, the other patients in a nursing home do have to be considered too.
if his needs exceed what the home can do then you might need to plan ahead.
If you feel what they're telling you and you feel that is an instruction then ok might just be they're keeping you informed of the situation.
Your phrase not mine " increasing aggressive" the staff may not mind but other visitors may have complained, just to so hard to know what's for the best, sorry. K
