I just want to cry

I don't know what's going on with my boyfriend. He's not the same person anymore. He's just shut me out completely for probably a month now. I'm hurting, I'm i pain because I don't know what to do. Now he's just acting like none of that ever happend and is still not opening up to me. I feel alone and I'm sorry for ranting but I litterally have no one else to talk to and I dont have money for a therapist. Can yall help me? Is there apps that can help me? I just need a peace of mind, I need my baby back.
