I need some advice on what to say to my beloved wife so that i can save my marriage?

start off with telling her that you love her. and say how much you missed her. tell her how sorry you are and give examples on how you have changed and what you will do different this next time around and follow through with what you say. research on depression and educate yourself. ask her what you can do for her to help her. give her examples of all the wonderful things she has done for you that you remember and be sure to tell her how much you appreciate how much she has done and what she has done. before you speak with her i suggest you read this book called the five languages of love. it will give you on how to love her more and what her love language is so she care respond to you. also buy her flowers and take her out on a date when was the last time you guys went out? tell her how sorry you are for being cruel and mean and ask her what she thinks needs to be improved to make your relationship work better. and sincerely listen to her then do what she suggests.
