Why does my sister in law tell secrets to me?
This is the 3rd year of my marriage life and I have a beautiful wife and a very hot looking sister in law (my wife's elder sister). Before 6,7 months She wasn't close to me at all. I mean those days she've rarely even smiled at me. Few months ago our two families went on a trip. After that she became normal with me and near past, she calls me at leisure times specially when her husband isn't around. Now, she tells private things to me and asks not to tell her husband about that. She asks me to keep secrets and asks me to call her when her husband isn't around. Is this normal?
Honestly, I like her. But I'm confused now. So I'm asking some advises too.
