Sorry I needed to let this out my chest…

My husband is sterile, we didn’t know until 3yrs into our marriage and we are going on 9 years on February. I do love my husband but sometimes i would love to have my own family. I’m 35 and i feel old already and sad. Im always sad. He spent his days working a lot( sometimes 17 hrs a day because he works doing events like festivals, raves) and when he is home i let him rest because if a suggest to go hiking or visit new places he says yes but than he says some other times. So I don’t argue i just let him rest. But i feel like I’m dying inside. I don’t know how to feel different or happy. I do things but I wish i have a baby to share my time with, to feel like I’m getting old but happy. We do have a dog and i love him but i want more and I can’t have it.
