Made my wife concerned for no reason

r/

I (37m) am very close to my sister (Andrea, 39f). She has had a rough past 5 years or so and has had a lot of therapy, and has evolved into one of the most grounded and mature people I know. I’m really proud of her.

I received a letter from Andrea three weeks ago unexpectedly. She thanked me for my support, and apologized for any pain she had caused me, as adults or as kids. I wrote her back saying I was happy to support her and no apologies were necessary, and was surprised she thought she caused pain.

We started texting about it, and Andrea said that she felt some guilt and uneasiness about some of our interactions as kids. Andrea and I were playful and affectionate and would wrestle and goof around, and also give each other back and leg rubs at night. She was worried that these interactions may have made me uncomfortable or that they may have crossed a line in my mind.

I reassured Andrea that I had zero trauma from any of this. (Which is true.)

I mentioned this conversation to my wife (she was aware of the letters and we talk about everything) and she now has a lot of questions about my relationship with Andrea and what Andrea was talking about, and I’m worried that I accidentally opened a Pandora’s box.

How can I reassure her that this is all a big nothing?

Tl;dr: my sister apologized for no reason and now my wife has concerns for no reason.
