Missing my Aqua ex

Hi, everyone!

My relationship with my aqua man has recently ended, 10 days ago. I'm a Gemini, if it has any importance. We have dated for almost 5 months, we had a really good time together, we had serious plans about our future together, we knew each other's family. in the last 2 weeks he started refusing going out with me, stopped texting me so much and eventually he said that he didn;t feel the same about me, about our relationship and that we were kind of monotone. i understood him, gave him ideas to change some things, to have other activities together, i accepted to give him some space and act like simple friends for 4-5 days. now i have to admit that i tend to be a little too pessimistic, i was angry and emotional when he said i couldn't do anything to have the same relationship because he didn't feel he would be that happy with me again, i kept pushing him and asking for a real reason why it all changed, because for me everything was still perfect. if we happen to see each other, he asks me how i am doing, he doesn't text me, but if i ask him how is he feeling, he never tells me this is the right choice for him, that he is fine, he says he is "handling it". i feel good, anyway, i am positive and i know i can have a happy life without him too, but he just had such a good impact on me and we had a real connection, we both felt it and i still believe in those plans we've made. i miss him more and more everyday and i feel the need to tell him that i'm up for a change if he is willing to try again, but he just refuses to talk about "us" under any circumstances. i would like to know if it's wise to wait for him to make the first step, if he feels like it or try to reach him, but i doubt that he would let me.... can an aquarius man tell me if i've hurt him or... why did he close the door out of nowhere? any chance to open it again?
