finally told our counsellor about the LS after 8 months... her reaction surprised me

just want to share and ask if anyones had similar. weve been in counselling for 8 months (brisbane, both 41) working on communication and a parenting crisis. specifically chose not to mention the LS because we worried itd derail things or shed judge. last session i finally said it. just blurted it. she paused, smiled, said "i wondered if there was something. so much of what youve described has the texture of an ENM dynamic. thank you for trusting me." i nearly cried. but now im wondering if we wasted 8 months by hiding such a huge piece of context. has anyone else hidden the LS from a therapist for a long time and then disclosed?? did it transform the work or did it just become a footnote
