Mentally drained, have no one else to vent to

Just found out last week I’m pregnant , now all this week I’ve been being mentally abused by fiancée , I am living in Alabama , but from Ohio. I’m stressed out to the max that I am , being told daily everything’s my fault, if I don’t change everything basically about me that I’m going to continue being treated badly, I’m trying to hold myself together because deep down I know I’m a good person, but I have no family here so my fiancées mother always sided with him. I just want the old him back , he used to surprise me leaving little notes, just text me to tell me he loves me , etc. I explain how it makes me feel and I get told I can never take up for anything I do wrong. But when I hit my breaking point of course I’m not going to be nice and I’m going to not act all sweet. I’m so mentally and physically tired . I don’t want to talk to my mom because all it will do is stress her out & I can’t even talk to my fiancée because he’s acting nice like a child and won’t even speak to me & if he does he tells me to shut up, or stop talking. I have no friends down here & no one to speak to.
