Kind of a Sex dream

Soo, i said the most silly thing to my boyfriend! Seriously! We have a long distance relationship and we meet whenever possible and i had a romantic/sex dream last night which the person in my dream was not my bf. There was someone else. And apart from that i said to my boyfriend what i saw. And obviously he didnt like it! (Why would he?i would have reacted the same) And i thought to myself why did i say it? I explained to him but i feel there is still sth there that he didnt like. I mean we have been together for 2,5years and i want to share everything with him. I dont want anyone else, i love him, his my person, he completes me. But i dont know now if this will change our relationship or not.

Any thoughts?
