OK, here's about 25 years' worth of experience dealing with an ENTP. You seem to really, really like him, so my heart went out to you. First of all, resist the tendency to read things into his reactions to you, because as much as you want to think you know what's going on, you probably don't (I'm just trying to encourage a little humility here, because I know INFJ's are good at reading people, but don't go there if it's somebody you're trying to start a relationship with). Next, give him some space -- Perceivers always like to feel they've got options and they're not cornered into something. Do everything you possibly can to resist the sort of internal intensity you're experiencing right now, because it will only get in the way. Relax, be light-hearted, use your INFJ sense of humor -- most people think it's weird, but ENTP's respond to it like nobody in the world. And most important of all, FLIRT, because ENTP's are big-time flirters themselves and they pretty much respond to it whether they're interested in you or not -- they sort of can't help it! As an INFJ, flirting may seem slightly dishonest to you, but if you think about it, you have your own unique sort of INFJ-flirtiness, that, again, most guys wouldn't be able to figure out, but an ENTP will find it very, very compelling. ENTP and INFJ are pretty much opposites, which creates attraction, but they're also both dominant intuitives, which is a bonus for you, because ENTP's, although fun-loving and sometimes seemingly superficial, really can't appreciate (and often have very little patience with) someone who's not intelligent. And frankly, I wouldn't encourage him to talk about his feelings right now, since there's an Ex, because, first of all, if he does, you'll probably get an earful that you don't really want to hear, and second, he needs to get away from his Ex emotionally -- so give him the opportunity to have fun, relax, and not have to think about her all the time. Good luck!
