Ex boyfriend and moving on (LONG)

I need to vent and get this off my chest and I hope it will help me get through this. I was in a relationship with this guy for 1.5 years. I loved him a lot, still do. We met on tinder and I didn't think it would last. I was away at college and he lived an hour away. I told him I was tired of getting my heart broken and if all he wanted was sex, I wasn't the girl. To my surprise, he was a gentleman. He held the car, met my parents and got along well, saw me at least once a week if not more. Things were going great and I was falling for him very quickly. Of course, we didn't agree on everything but we never fought. We always compromised in situations. I really thought he might be the one I would spend forever with. After about 6 months, he slowly stopped seeing me as much. He worked full time and went to school full time. He drove a decent drive for work and his classes were hard. I completely understood that he may not be available as often. We ended up seeing each other once every 2 weeks or so, sometimes longer towards the end. We still both told each other how much we cared about one another and wanted to make our relationship work. We had had talks before about breaking up because of the distance and his hell schedule but we always stuck it out. I started to feel like I was the only one putting in the effort. I know he was busy (understandable) but there's no way he couldn't find time in weeks to make the effort to see me. I sometimes felt like I was the only one fighting for us while he just did his thing. Eventually, I grew tired of fighting. I wanted more. I wanted a boy who will be there more often. Who I know is making every effort he can to see me because he loves me and hates being without me. I do believe he loved me like he said. I don't think he ever cheated. He's just so bottled up emotionally sometimes and it took awhile to learn the kind of guy he was in a relationship. So a few weeks ago he told he thinks we should stop seeing each other. I gave it one last try to make it work between us and it was basically a lost cause. He says he thinks I could do better. I thought I had prepared myself for this and would be able to cope, but I cry every single day. I miss him and I'm hurting so badly. I believe in the whole "let it go, if it's meant to be it'll come back." I have hope that whatever the future brings that everything will be ok and it gets better. But when? How can I speed the process up? How do I fix the pain inside me? I write poetry and here's an excerpt from one I'm writing "they say that time heals all wounds but I think my wounds are infected." I just want to be able to move on and be happy and not feel heartbroken every second of every day feeling like I just lost the love of my life. I'm scared I'll never love someone as much as I loved him.
