What to do?

I was trained to Pleasure and serve But my trainer wanted more at the time He was training me to take over for him. My trainer is died but his last words was I take his place. I have honored everything he has trained me as but this I am having trouble with this. I like serving I like being on my knees. I have a Handler that I serve and pleasur. I belong to him. My gawd we are married and I am still his. I know I have a dom side I know How to train I did it in the past. Like it no I rather Be a sub that serves and pleasures. But I hold Honor above everything I have Honored my trainer his teaching and my Handler agrees I should not stop Honoring him. How can I honor his last words and take his place when it means giving up what I enjoy the most?
