Recently found out two very close friends have started to meet up separately from the group, and friend A has told me they have both been discussing taking things further and possibly starting a relationship.
friend b confided in me a few years ago they had contracted Herpes. Made me promise to never tell a soul.
Friend A has recently got out of a very controlling marriage. Also friend A has 5 DC with ex that would become their soul responsibility due to nature of break up.
Friend A has only ever been in 1 relationship, ex DH.
Friend B has a track record of sleeping around, currently in long term relationship.
Problem is now I know they are thinking of taking it to the next level, and knowing that B hasn't told A of SDI, I feel like I owe it to A to tell them. But feel loyalty to B not to break their trust.
