My dreams are ruining my life.

For months now I keep dreaming that my fiance either leaves me for another girl or cheats on me and I wake up so hurt and it makes me so insecure when I wake up. He's not doing anything to make me think he is. Now I just don't trust him at all because of my dreams I'm bracing myself for it to really happen soon and I've become controlling and emotional all the time. He messes up alot and has in the past when we broke up. I'm so Sick of these dreams. Does anyone else have these dreams CONSTANTLY? Also I'm 11 weeks pregnant.

We don't live together and he doesn't really ask for sex anymore which is making me overthink. But he still tends to me a lot between his busy day.
