Re: What's your thoughts?
Where is your former sensei's 'Aiki'! With an attitude that you described he needs to review his 'Big' aikido (the way you conduct your life). I wonder if this is reflected in his 'small' aikido (practice/physical skill/technique)? Treat this experience as 'bad or incorrect technique' and 'small spirit'. You are better off on your new path, look forward and enjoy.
Good luck for shodan.
