You know her best. But I will say this...there was no reason she couldn't have kept you updated as to what was going on. No reason why she couldn't have even made you a part of it by asking for your opinions on his situation. No reason she couldn't have had you read over her shoulder, so to speak. I know I'm projecting, this is how I would have gone about it. No way would I risk damage to my relationship over an innocent exchange between two friends.🤷♂️
I don’t think I am??? I enjoy the time we spend. We do have a lot in common. She checks the big boxes with no cohabitation and no marriage. She’s a good person at heart.
From what I saw, she was just a sounding board for this guy and his failing second marriage 3000 miles away. It was nothing more then that. I know how to check to the degree that I can.
Maybe you two haven't made that solid of a commitment to each other, I don't know. Maybe you two even lead sort of separate lives with parts of your lives you keep private from each other. Once again, I don't know. But if that's not the case, if you two are committed to one another and expect transparency to keep trust intact then something is off with her.
