Dreams

Tia
Last night i kept dreaming that my partner of four years cheated on me with my bestfriend in my own home when she came to stay for my gender reveal scan ( she lives 3 hours away ).. i kept waking up and freaking out but no matter how hard id try to get that image out of my head i just kept dreaming about it.. and in the dream he didnt care what he did he broke it off with me first and was being a complete jerk a whole different person and started dating her in my own house.. i know its just a dream but what the fuck is going on with my head.. she is coming to stay in a few weeks for my gender reveal and im freaking out is this dream telling me something? I cant see him cheating on me? He just isnt that type, she has stayed before and nothing.. idk what is going on does pregnancy have something to do with weird dreams
