Need advice

So, my boyfriend and I are long distance. He doesn't have enough money for his phone so we can only text and talk through WiFi. Recently he got into an argument with his roommates and told me his friend(a girl unfortunately) said he could stay with her if shit hits the fan. She is also pregnant from some guy. But my boyfriend told me he was going to her house for a day to watch it because she had to go out of state. So okay, I can handle not talking to him for a day......its been 3 whole days since I've talked with him. He didn't tell me anything, when he was leaving or anything. Should I be worried or am I just overreacting? I'm sorry for such a long story. I am just so hurt and lonely at the moment. I'm worried hes not gonna come back.😢What are your guys opinions?
