Nightmares making me paranoid

Alyson

So I know it's ridiculous but my nightmares have been so vivid they give me anxiety and I wake up with headaches. There is a girl all over my BFs Facebook like legit she likes or comments on every single post, no lie. He says it's just cause they are friends and she's glad he's doing well and blah blah but I can't seem to get the idea out of my head that he just has all these girls that would come flocking to him if he ever left me or wanted someone else. It's seeping into my dreams now and I can't help but feel distant from him 😩 I'm 26 weeks pregnant and we live together but I can't shake this feeling at all. I've argued with him about the amount of girls he has on Facebook and this includes ex girlfriends but he says they were always friends and yada yada but I don't have a bunch of dudes I've had sex with all over my stuff. It just seems like a slap in the face or I'm just crazy but I'm really losing it. My hormones aren't helping and I can't go on like this :/
