Most Helpful Guy
I message girls I'm friends with and girls I like. I don't usually Skype someone unless I'm interested or willing to get to know them better. I don't like using Skype, so if I'm willing to Skype, it's because I'm probably interested.
If he flirts and then friend zones other days, it could be that he's not sure where he stands. He's probably recognizing that he's flirting and then doesn't want to hurt your feelings if he's not really interested in you so he sticks you into the friend zone again because he's trying to figure out what he thinks. I doubt he's playing hard to get, but it could be that he really is interested, but he's not trying to let you know for sure because he could be fishing to see if you're interested.0
