freaking out again.. (kinda long)

so after an encounter with someone who was very uptight, judgmental, and controlling, i let myself open up once again.
i ended up connecting with someone which ended up with us skypeing every single day for 3 months (he was working overseas).
he's perfectly ok with the fact that i'm bipolar and doesn't see it as a big deal. we have the same moral view, values, get along very well, and it was very easy to talk for hours until the sun came up.
i guess you could say i've been burned and i always keep myself in check while not letting myself get too close/attached, keeping myself detached. i know i'm only human and this was bound to happen, but i let myself open up to this guy since he proved himself to be worthy and now i'm regretting it and not i'm very frustrated and upset at myself.
he came back to the states this past sunday and we went on a date on monday which went extremely well and ended up covering all the bases... this never happens and i've told him that, but i feel like we know each other (as if we've already been on 10+ more dates)
he's leaving the country again by the end of his week for about a week/week and a half and said he wants to hang out again before this week (in which i agreed of course)
i know i'm just being bratty/unreasonable and he's probably busy with a million things to do since he's been gone for so long, but ever since he got back our texts have been very sparse/delayed compared to when we were texting before. i'm not upset or bitter at him, because in reality we're not even technically dating (yet?), but i'm more upset at myself for getting mad, freaking out, jumping to conclusions, and just overall being bratty (all to myself, i wouldn't express any of this). i try to keep myself distracted by going to the gym, finding stuff to do, but it doesn't seem to work to be honest, i've also been "trying" to talk to other people, but it just irritates me...

i'm so irritated/annoyed (with myself) & don't know what to do... anyone have any advice???
