I feel like I wasted 1 Year of a Relationship

My Partner of slightly over year just broke up with me today

To me, it came out of nowhere, we literally just met up yesterday, and while we did have a heart to heart conversation about them feeling emotionally distant to me, particularly bc I don't usually share a lot of my struggles and stresses I am going through, I was more then willing to change that for them

They are a person I felt like I could be myself around, that I didn't have to hide my very nerdy interests and someone who is just so kind and empathetic and I love to be around

But then, literally a day after I thought thinks were good, they wanted to talk.

Their Reason? We two are just too different as persons, with our personalities, interests and priorities not aligning 

And that's it, nothing I could do in their eyes to change or talk it out, and now I feel cheated out of a year

We knew each other before that, I never hid what my interests are or how I am as a person, how did change in a year?

And while I am very guarded on my negative emotions, it feels terrible to hear how that was their problem, how I don't share enough about my struggles in particular and how they don't understand me, especially when I put in so much emotional labor supporting them through their emotions, problems with their parents and other stresses in life, while they didn't tell me this until a day before they wanted to break it off

And not to harbor on priorities, like they didn't announce a week after we got together that they would be away for a semester abroad and we would have to be long distance for a while. And you know what? We made it work, I even drove out for weekend just to see them again. But I get criticized when I thought about maybe not making it to a small vacation with them and some friends, bc I wanted to go to a Pokemon Tournament the weekend after (I haven't even decided and was on the path to make both work out, but now that decision was made for me)

But all for nothing 

And I just wished they would have realized it sooner

Like, you couldn't tell we have different personalities after like half year? Or a month? Or maybe in the two years before that we knew each other?

I feel immensely betrayed and hurt, all the effort to be there for them

Especially the interests part, I already feel like I often have to hide my interests to others (how do you think people look at you when you say you love to go to Pokemon Trading Card Tournaments?), even if it isn't intended, it feels like another stab

And now I have to detach myself, we met through their brother, who is a good friend of mine and the boyfriend of my best friend, which make everything more complicated 

they were part of my DnD Campaign that I now have to put on Ice because they were heavily involved and I can't stand to look at it right now

I had to take down the picture frame their parents gave me as a present of us

My emotions are definitely heighten right now, early 20s and first relationship (for both of us) does that, I will get over it, and I will probably find love again that I can trust, but I can't help but feel frustrated and angry about it all, all that time I could have spend with my friends instead, I could have found a different person, I could have not been hurt for just being me

I definitely wasn't perfect, but don't jump "different personalities" on me after we've known each other for 3 years
