Is my bf cheating??!!

So guys I honestly don’t know but I feel like my bf is cheating on me. I don’t trust him because to my face he’s showed me that he’s very friendly around other women and idk but lately he’s been treating me like a straight up dick and I love him and I know he loves me. He always apologizes even when I’m wrong or right. But he’s a very sarcastic person and I honestly hate it! But lately he’s been treating me like a dick . Like his attitude completely changed and his pride is insane now like I honestly don’t deserve the way he treats me sometimes and he’s been telling me that he has many dreams of himself cheating with other women and right now I literally just had a dream of him cheating on me 😒🧐 ... is it me or something’s up with him??
