Husband left and hasn’t came back

We got into a really big fight over money, it was stupid. I’m pregnant and my hormones went everywhere and he got mad, grabbed his keys and started walking out. Stupidly I said “don’t ever come back if you leave.” He said “fine I won’t ever come back.” And left. I felt horrible. Tried to call him, tell him I’m sorry. But he left his phone here. Checked the bank account all night, he went to Walmart and Burger King last night around 7pm for dinner. I thought he would come back but he hasn’t. It’s been 24 hours now. He hasn’t used his debit or credit cards at all today which he would had to of because he would need to eat. I’m high risk and can’t be out of bed but I have to because we have a toddler. We have no food here for me (my daughter has food though) our animals are also out of food. I haven’t slept, I’m so sick with worry. I figured he must be with someone if he hasn’t used his cards. His mom HATES me though and said she didn’t hear from him but could be lying. I have no car, I live by no family or friends. I don’t know anyone around here. Any advice? I really need my husband back home.. I miss him like crazy

Edit: I’m 99% sure he’s with his mom. She won’t answer the phone. Which means we will end up divorced. She’s crazy and gets into his head. She hates me and they all make me out to be this horrible horrible person. Months ago we got into a fight and he went there, I didn’t hear from him for a week because they pushed him to ignore me and not come home to his family. He wouldn’t even talk to me until I went there and begged and begged him. I don’t have that option. It’s almost Christmas.. we have no tree. No presents, nothing. I’m so heartbroken right now

Second edit: I got ahold of his brother. Who also hates me, it’s confirmed he’s at his moms house. He has no intentions on coming back.

Third update: I talked to him. He came home and got us food. We talked and he said if I respect him he will respect me and not leave like that again. He got black out drunk and walked 2 miles to his moms house. That’s why he didn’t answer me, and didn’t call me because he was hungover. Thank you for all the advice.
