Somehow, I know that once he cums inside of her, I'll never have sex with her, ever again

Every night I dream of my wife, but she's in bed with another man. I see her up on the bed or the couch, while I'm on the floor. Sometimes I feel as if I'm dressed up in her clothes, while another man fucks her in front of me. He slides his massive cock into her, and she turns to me, giving me a look that lets me know that her body belongs to him now, not to me.

Somehow, I know that once he cums inside of her, I'll never have sex with her, ever again. I usually can sense that I'm wearing her bra. Sometimes I almost feel as if the cups are stuffed full, or that I have boobs of my own. It makes me feel as if I'm not a man anymore. Not as I wear my wife's clothes, and watch another man take her.

But the worst part of it all is that when I wake up, I have a huge hard-on! Lately when I'm in bed with my wife, I find that I can only get it up if I imagine this scenario. I tried to tell her last night as we went to bed, but she just said "Shh", told me to go to sleep, and that everything would be fine in the morning. It was as if she already knew.
