I'm a taurus... and when it comes to dating and love, I've been known to do stupid things. My stupidity always came from either something else in the way of what I wanted, or me trying to project an image that I really wanted someone to appreciate, yet done in a totally obscure ultimately pointless way. From your age, I'm assuming your taurus friend is young as well. I can tell you he's probably inexperienced, nervous, and uncertain about how to proceed. He likes you but believes there is something in the way in stopping him from proceeding in a "normal" way. He's doing this because he does like you, but feels conflicted between with what he wants, what he needs to do, and what he FEELS he needs to do. He's acting this way because he wants you to know he's still there but is stubborn and unable to express himself in a manner that is both mature and effective. Young taurus men are stupid when it comes to matters of the heart. He's doing this because he doesn't feel capable of approaching the situation without these ineffective measures. He's trying to protect his feelings, he's probably dealing with extraneous factors, yet he wants to contact you, and feels this is the best way, even though it's apparently non-sensical.
Ah, well in that case, being that much older... he's either nuts, or he IS playing games and probably has several people on the side. Your best bet is to stay away from him. Find someone closer to your own age. This won't turn out well.
