Now what? I feel so alone

It’s been 3 days by husband left me because I caught him cheating. He slept with other people. Well I technically kicked him out. I depended so much on this man. I’m going to lose everything and now I have to start over. I’m 20. I tried to get a new phone today because I know he can cancel the service on this phone at any moment. But I can’t afford it. I’m not working I’m a full time student. I have no credit and the down payment and monthly payments are so high for a phone, I just can’t afford it. I have no friends. I’m all alone. I feel like a pathetic loser. I want to be independent and strong. I’ve applied everything and have had no luck. Tomorrow after class I plan on dropping my resume off at some places. I have worked. I worked in high school but I stopped once I became a full time student in college. My husband helped me out a lot financially, he was paying my phone bill and gifted me a car. Now I’m left with nothing. He taking everything back. I got home and started crying my eyes out. I feel so alone. I feel stupid. I don’t have much saved up. I feel alone and sad. He has treated me bad but never did I think he would cheat on me. He is the type that if you’d saw him, you would NEVER believe how he actually is. He is always smiling and laughing, so nice to others, he’s so charming but he had a dark side to him. I thought therapy would help and he finally signed up for therapy but then I found out he was cheating so I decided to end things. What now? I’m so used to going to school then coming home to be a wife. I told him everything, now I have no one. I will never accept him back and I don’t even think he wants me back. I mad a stupid mistake and texted him saying how could he do this when I tried so hard to make him happy.. he never replied. I don’t think I’ll ever get closure. Now I don’t know what to do. I’d appreciate any advice, thank you
