Haha, As a male ENFP I would most honestly answer the OP: To win over an Male ENFP, all you have to do is be the object of their affection. We pretty much do the rest, and additionally project all of your weaknesses as 'soulfulness'.

Keeping us around? Be patient, don't point out our shortcomings, observe that we take everything critically, and I mean EVERYTHING. And it helps if you don't become boring, or try and change us into regular people. Women, especially the stable and wonderful kind that ENFPs need, are apt to try and fix our weird ways which only makes us feel even more remote.
I need some advice from you ENFPs out there... I feel like giving up on this ENFP guy, but something is keeping me from letting it go.
So, here's what the (long) story is : we've known each other since childhood, and he liked me for quite a while in our early teens, I liked him back,not as much as he did, but I was scared of anything serious that early, and I kind of liked some one else back then. So it ended. Which was really sad cause we lost the friendship too.
Until about a year back..when we got back in touch over this new blog he had with some amazing poetry. I had a blog as well, and we kind of kicked it off from there.
I never really thought of him as a lover, but something about how he wrote made me lose my mind. I was in love, with his mind.
So we began to periodically share what we would write with each other, and had a few very meaningful discussions.
After a while I felt like I wanted us to be more. I could sense though, that he might not be ready, he seemed hurt from a past relationship.
After some more time, he invited me to meet and since we live in opposite parts of the country, it was hard, but we met. We spent the afternoon and night talking, and it felt blissful! I always felt like he made me feel like I was the most important person on earth. (I've come to figure out that ENFP's try to make pretty much everyone feel like that though, so, I guess it wasn't that special). Anyway, we had a short kiss and that was that. He was very sweet.
I left the next day, and that is when everything changed. He became distant.
I confessed how I felt by writing him a short poem, and he said he felt the same way...the conv ended there, but he kinda disappeared after that, almost like he didn't want to talk anymore... So why did he lead me on?
I stopped initiating conversation after I repeatedly felt he lost interest.
And weeks would pass and we wouldn't talk, and out of the blue he would text me a long paragraph about what he was going through, like nothing had happened.
I tried to be warm and kind eventhough I felt very confused..
He would write me a few times in a row in one week and occasionally I would initiate a conversation too.
Occasionally he would drop some lines that would be very straight forward about wanting to be more than friends, heck, a few times he was so straight forward that I was almost certain we had gone a level up, not yet saying the word gf or bf, but pretty much there.
Out of the blue he would disappear again. I was hurt. I let it go completely after that. I figured if he wants me he'll man up.
He kept writing me periodically after that, short thoughts, a link to a song, or asking me how I was (but most of the time he did that just so I could ask him back. Our conversations were 80% about him, and it started feeling like he was using me to get attention and to feel important). Yet I know his heart, he is so kind, so loving, why would he do that?
He was often very flirty, and if I would respond back the same it almost seemed like he would freak out and disappear. He often made me feel like I was the one who wanted us to be something and like he was just going with it when he felt lonely.
I confrunted him twice. the first time he assured me that he liked me too, but that he was afraid of rejection, like in the past. So, I apologized for when we were teens and I hurt him with my indifference. We had a great conversation and it felt like we were making great progress. But of course, he disappeared for 1-2 weeks again after that, leaving things unresolved as usual.
One day he asked me if I wanted to meet again as we were passing through the same city coincidentally in the same day. I agreed. We had a good time, coffee, walks, and talks, but nothing about us, he didn't bring anything up and I didn't either because by now I felt like he was just playing with my emotions. I tried to ask him about him, his story, but he looked at me and didn't say a word. I almost found it rude.
We didn't talk much after that meeting. Just some Merry Christmas messages and a few insignificant other conversations ( mostly initiated by him)
Here we are, a few days back after again not talking for a while, he wrote me, and he was being very sweet and flirty and made me feel really special and he mentioned wishing I was with him in his life, that I made him want to be a better man, that there was something about me that made him so drawn to me. I told him that I made my feelings clear, and that he is the confusing one, saying one thing, coming to me with all this sweet talk that he never backs up with action and diaappearing afterwards. He said he felt like I was sending mixed signals and that he was scared to act. By now I was very upset, because I had been always kind and always there for him dispite his inconssistency. I told him that all I want is for him to be straight forward with me, that all I wanted was to get to know him, not necesaarily to be an item so fast, but that he always pushed me away when I had asked about him, his story. And kept disappearing and leaving me hanging. I told him we should remain friends, and if he wanted us to be more, that he would take that step, knowing how I feel.
This was over a week ago and it seems like he has disappeared once again.
What am I doing wrong? I feel like he is taking advantage of me. Saying all the right words but doing nothing. I hate things being so confusing and unsettled. I need stability and realness.
I feel like giving up so often but I just feel connected to him like I've never been with anyone else. He is truly special, and rare. His heart is precious. But I'm so tired of all this back and forth.
What's going on in his mind??
All y'all ENFP males (or females) over here, would you give me some tips?
