Miscarriage ruining relationship

It has been almost 4 month and every single day since then I’ve cried at least once. We have had sex maybe 4 times since then. It’s been 3 weeks since our last time and I can tell he’s getting irritated but I can’t bring myself to it right now. I’ve also been so depressed I don’t want to go anywhere with him and he gets upset bc I know he just wants to go places with me to help me but every time we go somewhere I see a pregnant woman or a new baby and I tell him to take me back home.. It’s just getting harder every single day. Has anyone else been through this? I have posted about this a few times but it’s getting worse and I can’t stop it 😔 I feel horrible bc I know how bad he wants me to be ok but I just can’t.
