Being a husband, it is your moral responsibility to make sure your wife is mentally and physically fit. She is your partner and you owe her care and attention, just like she owes you.
Always make sure that your lady is calm and has peace of mind. Listen to her when she talks, and try your level best to understand her. If you cannot, carry on with the conversation until you reach a mutual agreement. Show her that you care and do your utmost to ensure she is happy and content with her life. Encourage her and support her choices and decisions. In this way, you will be doing wonders for yourself and your relationship.
