He's a Playboy
If you have to question whether or not you're the only person in his life, then your suspicions are probably on the right track.
You might consider yourself someone that likes the exclusive type of a relationship…that’s great! Well, he’s not. Unfortunately, a majority of Manhattan’s eligible bachelors fall into the same category. Over time, if he hasn’t expressed that you may be “the one,” then don’t bother putting all of your cards on the table, because you might lose a pretty valuable hand in the end.
