Hello Friend, Good that you are seeking a help here. I understand your concern.
You both need a marriage counseling to sort out any understanding gaps or differences of opinions in the relationship. Holding such issues within your self is not going to help.
If together, you at least need to take a counseling support first to mange your emotions and depression to handle your day-to-day life for your kid.
