I love my husband but....

I love my DH with all my heart, but I don't talk to him about how sad I am that I'm not pregnant yet... I used to think it was me & I freely talked about my concerns & sadness about ttc.. but after testing we found out it was male infertility... & IVF is our only way. I'm strong for him, supportive, & love him more now, but how can I talk about how sad it makes me that we're not pregnant, w/out making him feel at fault?? I can't.. so I keep it to myself because it's not his fault; he wants a baby just as bad as I & I dont blame him for this, but I can't tell him my fears w/out breaking his heart.
