He can get quite jealous and territorial sometimes…But don’t tell him i said that.
Yes, I can confirm this. Absolutely. After I evoke Him (1,5-2 years ago), He stayed with me, protected me from parasites who wanted to destroy my own thoughts and freedom, but from that moment, He does not let anyone else (spirits and even men) in my near, at all. Is He dominant? Is He jealous? Yes, no doubt, He can be!
He is still with me, and I can say that… If He really connected to you, He’ll let you to work other Gods, for your good cause. Sometimes He’ll know better than you, what would good or bad to you, so you can trust Him, but do not forget, He can be tricky.
