Like Nancy said, you should honestly pick up the phone and talk to him. Tone and intentions are hard to read from a few digitalized letters. I think that this whole dating thing has seriously suffered with the introduction of texting. lol If it s just 2 days, then don t sweat it. He said "Ok" - I mean us guys sometimes do not feel the need to insert a lot of words into what we say. "OK" gave you your message - he d like to do something again sometime. Don t read into it anymore than that unless he starts to flat out ignore your texts or calls. Additionally, a lot of guys are taught to not contact a female right away after a date (generally one to four days), so if he hasn t initiated contact after that, then I d say he lost interest, or as a more likely scenario, he never had interest at all and he was just stringing you along. This stupid "hard to get" technique was thought of by some dating "expert" YEARS ago who probably had little to no ACTUAL experience in psychology or any kind of University/college. This technique is done because it supposedly gives the woman an idea that the guy has a life, is interesting, and isn t always thinking about the female. This is such a misconception though, although a lot of guys (AND GIRLS) do it to their dates. Also the problem is, when this game is played, nobody knows how to play it CORRECTLY. Hard to get should not be forced - it should just be something you do to not fixate on a female or a male too much. For example, if I m busy with studying for an important exam in my University and my girlfriend wants to talk, I ll tell her "not right now" for that legitimate reason. She ll know that while I m her boyfriend, that I also have a life. That s NATURAL hard to get. If your date is doing this game without legitimate excuses, and just to correspond what he s read on "official" dating sites, he s playing it HORRIBLY WRONG. Any more than 3 or 4 days, and if he s still acting cold, then you can assume that he s lost interest. Until then, go out, find another date, have fun. You and the first guy are not exclusively dating yet so perhaps you can keep your options open while you re waiting.
