I am engaged to be married. I have been with my fiance for 3 years. Twice while sleeping my fiance has said his ex-wife’s name while dreaming. By the other things he was saying it was obvious that this was a sex dream.I felt very hurt by this and concerned that perhaps he has feelings for her still. He has reassured me that he doesnt and says he feels really bad about it but has no recollection of the dreams.Is this somehting I should be concerned about? They have been divorced 5 years. He dated a few people in between meeting me and his divorce. Thank you
