I need help.

It’s been a month since I’ve had my miscarriage. The pregnancy wasn’t planned. My boyfriend was relieved when I told him I miscarried. He was happy and still doesn’t understand why I’m so hurt over it. Before I got pregnant I was not interested in having a baby right now. But now it’s all I think about. I even bought a car seat and some baby clothes.. even though I lost the baby. All I can think about is getting pregnant again. I spend hours looking at baby pictures online and I feel like I’m crazy. I’m embarrassed. My boyfriend thinks that I’m crazy bc I want to get pregnant again. What do I do? I’m dealing with this all alone because he does not care about what we lost. I feel broken and just want to have a baby more than anything in the world. But he isn’t ready. What should I do?
