I haven't cried in years

We've been married 8 years going on 9 in couple weeks. My husband knows I suffer from infertility issues but never brings it up or doesn't try having conversations about it especially when I want to talk. We are 29 and never been pregnant. I've worked really hard to help him get where he is but now he's walking around like his shit don't stink.I'm so ready to walk. I feel like packing up my bags and never look back. It hurts that all he says is, make an appointment and he will go but shows no interest whatsoever. I'm ready to leave it all behind and start fresh and paying for my treatments myself. I have a supportive sister, dad and extended family around me. All my 8 years I've fought to keep his head on his shoulders and build him up but I feel like he is never there for me emotionally when I need him. Money isn't everything, and if  he thinks I'll fight him for materialistic things and money he is wrong. All I'm worried about is having a healthy body and strength to continue to work and save for my future baby and I. Today, I found myself crying and actually admitting to myself that he shows the signs of a man who doesn't want to perhaps raise a family of his own or have children. It's something I've always wanted and know deep down in my heart I will be an awesome mom! I use to dream about the day we have our own children together and everytime I think of it I cry, I'm hurting so bad. I never knew I can feel like this. Whenever people ask us when we will have children or brings it up he brushes it off with his beautiful  big smile. He knows how much I love children and I just feel like he doesn't care.
