So my husband commented on a social media post to the sister of a childhood friend. Obvs I could see this. Then she says , I’ll inbox you. So I know they have been talking by messenger, but he has never mentioned it to me? Surely that’s strange? Back in touch with childhood friend and does not mention? So I was a bit sneaky and I did go onto his social media profile and unfriended this person. However, just seen message pop up from this woman; and they are friends again om social media, but still no word from him about it. (Not friends with the childhood friend or talking to him but is to the sister) people help me, am I being stupid , do I just let it go, it’s innocent right ??
