Me and one of my best friends has a sort of fling/flirtation last summer and slept together a few times. He was talking to my best friends older sister at the time as well and they’re now a couple. We stayed really close friends and it’s all been fine except for a few comments here and there that have been a bit awkward, but we kissed the other day for the first time since they’ve been together and even laughed about it the next day. We then both felt extremely guilty and decided to never tell anyone. He then drunk phoned me to tell me that he didn’t regret it and that he knew there was something between us. He spoke about wanting us to sleep together again but this morning couldn’t remember anything. I know it’s wrong but I think I’ll always love him a little bit more than I’m supposed to and just needed this off my chest.
