boyfriend probs

My boyfriend/baby's father has been living with me at my moms and then he just decides to move out. He says it's my family and that he still wants to be with me, he just can't live here anymore. He moved in with his aunt and I really don't know if I can trust him now.. our baby is due in March and I'm scared he's going to leave me. To top it off I've been stressed about everything lately and just don't know what to do 🙁
