It's that. How about talk to her and get a feel for her personality.
...and if she was flirt'n, that doesn't mean you freak out and run the other direction. It just means she likes you but you don't have to like her back esp. if you are married and truly love your wife. Just take it as a compliment.
Well i've have many other encounters with other wives, and it wasn't just my imagination that's why I assumed this case to be the same. Lets just say in other cases, married women who I thought liked me ended up sneaking out alone with me before at night....but don't worried nothing happen.

Im not trying to prove anything here, just sharing my problems.....c
an we put an end to this topic.
