I get a lot of questions of women asking me how to know if guys like them. This is a question that I get shocked at because I used to think that guys are very transparent but they're not so let's fix it.
So, the way to deal with guys that are showing interest but not grabbing you is to lose all expectations and to not give them any attention until they ask you out.
If you want to know if a guy likes you, don't initiate any contact. Be distant if you're talking to a dude and you want to know where you stand. Just completely pull back and make him feel that he's second in priority. The reason you're going to do this is that when you validate a guy, he'll feel so validated by you that he doesn't feel the need to show you how much he likes you. So when you don't validate him and you're suddenly too busy around him, it's going to make him wonder if he's losing what he had. By him trying to keep you, that means he likes you but if he pulls away and he doesn't put in the effort to initiate contact then that means he didn't like you that much.
Now if you're working with the person, all you need to do is be friendly and polite but don't initiate contact. Do nothing.
If you're talking to a guy and you're at work with him and you want to find out if he likes you, notice if there's any change in his behavior if you say you've started seeing someone. If he starts to ask how your day is and how the guy is, that means he likes you.
