i've been having alot of sex dreams lately, most involving me cheating on him, which are so much worse emotionally even than when he cheats on me in my dreams. i actually called him up one morning and was so upset because i dreamt he fucked his ex, who has been in and out of the picture (she texts him alot and calls occasionally.)
i called him, told him about it, and asked him, 'so did you fuck her?' he's like... what? this is ridiculous. which of course made me freak out even more. i was like 'just answer the question, yes or no!?'
he said no... i ended up being depressed the entire rest of the day. felt like dying. shit!
all over a dream. i have intense, dramatic, lucid dreams however. usually nightmares.
its just a dream.
try not to stress yourself over it. but i would talk to him about it if i were you.
