hi serafina, sorry you're going through this
i'm ENFP, but maybe some of this can be helpful anyway!
I would say that NFP's in general, are rarely every truly done with someone.
in general, someone has to
really offend us for us to shut them out completely. like down-to-the-bone offend. i very much doubt that you have gotten anywhere near this stage with him, though he probably is feeling a bit hurt and confused after your "jerk" comment and then avoiding him, and probably is unsure as to how to proceed.
We kept talking and flirting through text after that and a week later he called asked me out again. We decided on the following Friday night. [...] That Thursday he never confirmed our date and I began to get nervous. I tend to be a planner and had been invited to two outings which I declined because I made plans with him but now I was not sure if he was going to come through. On Friday at 2PM my phone broke and I got online and told him if he wanted to go out he would have to contact me through FB... I was super anxious at that point with my intuition telling me that he was backing away but me not wanting to believe it... he replied that he had to get packed for a fishing trip (which he had told me about) and couldn't go out and that he was sorry. I said, "oh wow you are a jerk." and logged out. Half an hour later I had cooled down and wrote to him apologizing for calling him a jerk but that I wish he would have told me this sooner. I said I understood and wished him a good trip and apologized again. I never heard back from him.
maybe i'm reading this wrong, but it sounds like you guys decided on the date, then you wrote him and said that if he wants to go out he'll need to message you? i think maybe there was more going on than this... but if you messaged me something like that after i thought we'd already set a date, that would make me feel like maybe you weren't taking me seriously and would make me kind of confused about how much you really wanted to go... and then to get called a jerk after that would be a bit startling (and dates are sometimes just less "set-in-stone" to Ps than Js... even with the people i REALLY REALLY love i run late sometimes because i am just lame like that...). unless, of course, you guys had previously agreed to confirm later in the week, in which case never mind.
either way, to me, it sounds like things are a little bit warm-and-cool on both ends... like you're both a little unsure and periods of warm close personal contact are followed by fairly long gaps of cooler downtime with just texting. it's not really a close close relationship, so i don't think i would be very worried about the time gap... on the other hand, he might be a little ambivalent towards calling - kind of awkward after leaving things off like that - but he might interpret your last message as you wanting him to call, but he might be hesitating because he might not really know what to say when he calls, you know?
my thought, and i have no idea if you will like this or not, is that perhaps you could leave him a little handwritten note and maybe a flower, and just say something like how you're sorry for the misunderstanding, and would really like to keep seeing him if he still wants to see you too, but would understand if he doesn't. that should elicit some response out of him - and if it doesn't, then you also have an answer.
my other thought is that perhaps you could make another cute comment on his facebook, and see if he responds.
i agree with huxley's point that you don't want to seem clingy, but i don't think the message on your end as it stands is necessarily 100% clear that you care for him as much as you do, and i think that you certainly still have a chance with him as long as you openly communicate, as nebbykoo said, that you do want to be with him.
so i think basically make it very clear that you want him as more than a friend and then leave the ball in his court.
good luck!!
