I know you have made your decision but donnot enjoy it. You cannot be happy and stable if you are uncertain of your decision and people around will notice your feeling especially your husband if he still loves you now. Also after arriving Canada you will face lose of confidence if you cannot find a job that would be fatal for a successful woman as you and then you will regret for you current choice. Think it over before your choice and take the responsibility of the way you will act and determination is indispensable to get your aim. Hopefully it will leave no regret in your life.
Try to be happy and God bless you.
