Let's say you and your gf have been dating few months. A first you thought all went smooth.

However, u realize that your gf still misses her ex. She still has photos of them together in her old phone and she will look at them privately. She also checks out her ex insta, Facebook and WeChat for updates.

Not only so, she will also ask for other mutual friends his current condition, whether he is good financially and socially.
