Do not nag him incessantly about doing the right thing. You will just annoy him.
Do not cry and moan to your friends or sisters about your difficult situation. Talking trash about your husband will only hurt your marriage.
Do not threaten or deny him love making because he does not want to be open to life. Nobody likes to be threatened.
Do not try to prove to him that babies are cuddly, cute, and wonderful. He still remembers the sleepless nights.
Do pray for him, over and over again. Pray for yourself also, pray for guidance, pray for courage, and pray for patience.
Do seek advice from a Priest or Spiritual Director. They can help you more than your friends can.
Do talk to each other. Holding things in will only lead to resentment. Resentment is a b*t*h.
Do love him. Love him for who he is, who he was, and who he will become. Love him until it hurts and then love him some more.
Do trust God or pray for the grace to be able to trust Him. He has a plan for you and for your marriage. TRUST Him.
