Losing hope

My husband and I have been trying to have a baby for 4 years now with no luck. I have pcos so it's been difficult. We finally got the appointment for fertility specialists coming up in less than a month. Now he decides he's ready to move states and go to school. He will be done in 2 years, and wants to wait until he graduate to start trying for a baby again. Im happy but sad about this. I've been begging him for year's to go back to school, and he never did. Now he waits until we're about to get some help to say this. He won't be working while going to school, and I can't handle the little bills we have now plus a baby and daycare if we went through with treatment since my job pays nowhere near what his does. I feel robbed. I've suffered in silence about my struggle with infertility, and just when I felt like I had some hope of being a mother soon, he ripped it away from me. How do I cope with this? Im mentally losing it right now, and I think I might have a full blown meltdown
