I think he's just happy that you exist... the stereotypical ENTJ is 'surrounded by idiots' (this is how the ENTJ feels like

), and so if someone comes along with half a brain and a big heart, then thats something to be cherished... I get all soft and giggly when I encounter such a beautiful person.

you should really realize what kind of a compliment this is! It means he finds you one of the most beautiful persons (beautiful inside and out) that exist
If he thinks this of you, then he would have no problems having a relationship with you more than friends. But don't get paranoid about letting him down or anything... if he thinks you are this beautiful, it really doesn't matter if youre a friend or a lover

He just wants you in his life.
I get angry though if someone is unclear about the kind of relationship we have -- if I have a female friend, I don't want her to be all over me and ask things she asks of a lover but give back what she gives a friend - thats not fair, so don't do that.
Be a friend or a lover, not something in between.
You decide.
PS: ENTJs can be overly nice sometimes, to make up for their regular unaffectionate asshole act. We'd like to be nicer but we can't, we really really can't be as nice as you... not all the time anywayss
