Ectopic pregnancy

On Aug. 11th my fiancé and I went through an ectopic pregnancy and it's so difficult... Does anyone have some good ways to cope... I can't walk through the baby isle, I can't look at pregnant women and when I hear a new born or an infant cry, I burst into tears... My fiancé is so depressed and full of anger. He blames himself... It's been putting so much stress on our relationship... We love each other greatly, but we still are having a very hard time... Please help...
