<human>: Give me the gist of the text in a nutshell

Hi /r/relationships,

I've been with my SO for two and a half years. We met when I was just finally recovered out of an emotionally abusive relationship, (and by recovered I mean finally leaving my house and trying to meet/trust people again.) 

Without a doubt, he is one of the most amazing people I have ever met. We clicked like no other, and we were eachother's best friends before we got into dating just a couple weeks after knowing eachother. I trust him with all of my heart, I truly do.

However, he has ALWAYS been the one in the relationship that "loves more." He is insanely affectionate, has written many a poem and song about me. Our relationship became popular on social media because of this (within relativity of our location.) 

We've never had a ton of problems within our relationship, either. He has planned to stick around for a long time and even speaks about marrying me. At one point in time, I thought this is what I wanted. However, a large life changed occurred where I am away from my abusive family and enjoying a bit of solitude - and suddenly I feel as if I no longer wish to cling to him. I don't find joy in the idea of sticking with this man for the rest of my life. It's not a sudden feeling either - it was creeping up slowly as this change was happening. He is my best friend and I can spend every waking moment with him, but the key thing: I feel as if I've never ever been alone before in my life. And I feel as if being alone instead of being dependent on someone for at least a period of time in your life is a key to development.

He would be beyond broken. I've shown no signs of feelings this way except for the occasional talk about it, but he's adamant that we're in love and will stay that way. And the truth is - I am in love with him, I just don't have eyes for the future anymore like he does. I'm terrified that he will end up being "the one who got away."

Sorry for the ramble-like post.
<bot>: How should I go about breaking this off with SO, [21M] without making it sound like there is anything wrong? Because there isn't. I just need to be alone.
