I think my fiance is cheating on me

He came home at dawn today the night before he didn't then he's rude all day ling, picks fight a with me and does everything in his power to make me feel insignificant, powerless and finds faults in every thing I do or say and when I ask him what hes been up to u straight out lies. He says he doeant want to break up and wants to go to counseling. I don't want to walk down the aisle with a liar, a chest and waste time money and energy into something that's ffoundation has been broken. It's not all me, it can't n because I'm the one who is at j one waaaiting for him.he stotally low interest. I know he's sei by other women but forforbid we amicably break up and part ways. I'm not allowed to even speak to some people but he does whaatever the fuck he wants. He doesn't touch me anymore and I don know how to get away. He's causing me a lot of unnecessary stress that I don't need, I am facing canc we and if I have to lose my tits in top of this and have all the stress of that US rather be alo ne. Is he just a sick fuck that enjoys torturing people?
