SO confused by Aquarius guy- need any & all advise

Ok so here is a little back story-- met this guy a while back & things were SO great right from the beginning. 1st date was like I knew him forever & lasted hours. U know that feeling u get when u just KNOW they will 100% call you the next day?-- I had that times a million there was NO doubt in my mind & the next day came & there was his name lighting up my phone. 2nd date was just as great and so on. First few months we talked everyday made plans to hang out all the time-- he called to include me in a lot of his plans with friends and just generally showed a lot of interest in talking to me all day & seeing me. 3 months into this work picked up for him & the everyday all day chats were every other day & the change caused me to doubt the relationship & where it was going. 3 months and there was still no commitment & the onset of not talking every single day really threw me off. I think bc of this I started acting differently & really started doubting everything I said, how I acted everything a girl would do when feeling insecure about things. I dont know if something really happened with his feelings at this point or it was me pulling back because the norm for us changed & I felt weird about it especially since I felt after 3-4 months there should be some sort of commitment coming from what we were doing.

Another month or so passes & I still felt the distance, & pulling away. I felt like the one who was always starting conversation first & making the plans. I would always feel this awkwardness about us until we were actually together hanging out because we always had a GREAT time when we did anything together. Always laughing, teasing each other, talking about serious stuff and always had the best sex. This went on a little longer until the holidays (yes this is ALWAYS the make it or break it right??) Well they kinda broke it.

Long story short I got a long message basically saying what a great girl I was & that I deserve more & its not fair to me what we're doing & he doesnt wanna string me along anymore but really wants to be friends but just isnt looking for a relationship for like 6 months bc he wants to concentrate on studying for a huge certification. So we agreed to remain friends..literally 2 days later hes already chatting with me (no time for me to heal). We starting talking still but once a week maybe...2 months go past & we wind up making plans to meet for a drink-- we end up sleeping together & have been since-- now this has been 4 months- he even ended up making time for me when he was studying & now the test is over & the 2nd weekend he was looking to hang out-- I dont know what to think at this point. I would think he'd try making more plans with me now & maybe try to start things back up but now I just think I need to officially walk away despite how amazing we get along, the fun we have, how well I get along with all of his friends, our shared interests & sense of humor & amazing sex we have.

Sigh... what to do... I've given him the opportunity to just walk away from me when we first broke up but he continued to contact me & then once we started sleeping together again it was downhill for me because I decided I was just gonna do what I wanted to do & contact him whenever I felt like it but of course now I cant lock away those feeling anymore & they are creeping on back!-- Damn those stupid feelings!!!! I am an aries girl I should be cool with this relationship shouldnt I—

Ive reads so many things on Aqua guys... why do they do this?! Go real hard & strong in the beginning get us girls allllll wrapped up in the moments of perfectness & then pull the cloth out from under us & we dont even see it coming?! Are they all like this?? Did something specific happen or do they all think they want the relationship & then when things get serious they run away?? Then feel bad about it & keep you around to not hurt your feelings or is it keeping me around because they just cant commit for nothing!!!

Help
