Don’t know what to do.

I’m almost 10 weeks pregnant and have a 13 month old. My husband just told me that he doesn’t want to be with me anymore and I have no idea what to do. I’m scared to be a single mom with two babies but I’d also be losing my best friend. I admit I haven’t been the greatest wife having a baby is way harder then imagined and I haven’t given my husband any attention. We have fought a lot and pushed each other away and now I’m at a loss of what to do to try and get him to come home to work everything out. I never thought I’d be this sad and upset while pregnant. 😪
