I was hanging out with my best friend and her brother, who has autism. He is nice and so sweet. We were sitting on the couch and then he kissed me. I didn’t know how to react so I did nothing. I am in a relationship with some one else and i am happy with my current relationship. I want to let him (my best friends brother) down easy without making him upset. I would like to keep a friendship with him but I don’t know how he will react. I told my friend and she doesn’t know what to do either.
