Figuring out what to do part 2342

So I finally let the entity talk to me and he basically said he's not going anywhere, ever, so it would probably be smarter for us to choose to get along rather than fighting constantly. I don't think it's fair or ok that he just gets to waltz into my life, say I belong to him and then that is just that. I don't get why I can banish him but not keep him gone.

I was even at the point of desperation where I was thinking of trying to get some other spirit to protect me somehow but what is the point? If not even God keeps him away 100% of the time what other spirit is going to hold up?

I wish I could find out why I can't keep him banished. The longest I can keep him away is like.....a month if I'm lucky. Theoretically I could just do major banishing rituals every damn month when he comes back but that is so exhausting, the major banishing processes take weeks to do and he fights very viciously.

I have been to churches & healers. The "healers" were a joke & did nothing. Having a priest send him away made him very angry and he punished me very badly when he did get back. But the priest didn't even send him away as long as I have. I think I'd need someone genuinely experienced with exorcising very powerful evil spirits. Which the number of those people that exist are very few, and none of them are available to me, lol. So to everyone who is like "just get an exorcism!" Find me someone qualified & willing 😑
