well... lol I'm not sure why you're asking this in the INTP forum, daylight... the differences between INTPs and INTJs are
very much superficial.
The one thing that I think is true about INTx's in general though, is that you'll
never get any initiative from them in relationships. In INTPs case at least, I have no idea how much physical contact is normal in any kind of relationship, so I just kind of mirror whatever the other person does. The (two) INTJs I know are way too shy to start anything themselves, and would sooner sit and wait for a decade or two than actually make a move on someone. The male gender stereotypes aren't kind to us with respect to relationships in any way that I can think of.
Since he tells you he loves you, I'm guessing he just doesn't know what to do with you

. ENTJs are good for pulling the INTs out of their shells, though, because you're easy to communicate with and don't usually listen to the culture's ideas of how a relationship "should" be... or at least are willing to shelve it if there's a better way. Go get 'im, tiger
