First, is your friend available? If your friend is currently in a relationship or even getting over someone and is confused about his or her feelings, then don’t make your move just yet. Otherwise you’ll look like you’re trying to seize an opportunity, which could leave her or him feeling betrayed. If, however, you spend lots of one-on-one time together, your interactions often feel like dates, or they have a romantic energy about them, those are good signs that you could become something more than friends.
