I am a dog ( metal) while my husband is born under a snake year.

I find my husband lately is cold and easy get frustrated when you trying to talk or say anything . Noticed that he like to flirt even in my presents

and leave me on the bench and sit beside with some lady who is even married and barely acknowledge I am around. It does hurt my feeling and want to know if he still love me or what is the reason why is acting inapproriately. Also he keep secret with his cellphone password which is not used to be.
I dont keep secret with my cellphone password but he does. I want to know if he is cheating with me in our marriage? What 2020 year await for us ? Are we going to get divorced I am not sure also how I can take this any longer esp. this type of treatment in a relationship?
