This is a photo on my (f28)Instagram. My brother in law (m42) reacted to it in DM, and said the above. I feel I replied normally, but now my sister (f39) apparently saw the message and is saying that I engaged in hot discussions with her man! I am myself married and I feel so bad now. I told my husband who said I did nothing wrong. Any idea how I could approach my sister ?
Some people, when finding out that their husband is creeping on their younger sister, might reject that idea and save their marriage. That’s just how brains work.
If her brain thinks it’s in her interest to blame you, probably talking to her won’t change that? Maybe but in my experience you can’t reason people out of unreasonable beliefs.
I’d not approach her, I’d wait and see how she is after some processing time.
