@SW-User my sincerest apologies to you and my condolences for your husband.
His high spirit energy is still with you, but he himself could may as well passed onto another plane of existence. What happens in certain beliefs with that is, when you’re really missing your loved one, if you see a cardinal anywhere near you ou of nowhere, that’s them. Sending you a message from heaven. Death is natural and we all are headed for it so it’s best to make the best of what life we have while we are here. Meaningful relationships, connections, helping others and being the best you can be.
He loved you beyond unconditional til the day he took his last breath and after that his soul was with you til he had to cross over. Don’t ever sit and feel left back or worries and lose faith, anytime you down and sad, and you feel that warm sensation or feeling familiarity around you, that’s him. Giving you a hug and letting you know it’s okay.
