I (18M) recently broke up with my GF(19F). I'm stuck in this limbo of wanting to keep fighting for the relationship or just letting go. I'm not too sure where I should go from here?

My girlfriend and I had been for a little over a year at this point and we had been introduced to each other by a mutual friend because she showed initial interest. So recently my girlfriend had been acting a little off and I noticed but she had gone through similar things and I'd told her she could talk to me if she needed it. She broke up with me later that week, on April 17th, saying that she took a look at our relationship and decided that she couldn't see a future, our relationship not lasting long-term and that she'd like to remain friends because she thinks we're better off like that. She listed some reasons being our love languages not aligning and her having doubts about the relationship. She had never brought any of this up to me prior and we had never had any fights or major arguments (this is what's messing me up the most I think). I considered us to be in a very healthy place, relationship wise.

I feel like all of those issues are something that we could've fixed if we had just had a discussion and talked about it and had a conversation before breaking things off between us. I really do love this girl, she's got everything I've ever wanted in a girlfriend. She's beautiful and has an amazing personality that charms me to no end. She makes it feel easy to be me around her and I don't have to hide anything. I want to keep her in my life because I think so highly of her as a person but I'm not sure if I'll be able to do it as "just friends." I want her to be happy above all, but I wanted it to be me to provide that happiness.

Now I'm stuck in this in between where I want to keep fighting to keep her in my life as someone close to me, or just respecting her wishes and letting it go. I pictured so much with this girl and the fact that it ended so suddenly, and I don't really see anything to "fix" is destroying me. I'll take any advice on how to move forward with my life and this issue, but I'd prefer nothing that relates to my age please, this is a girl I love with all my heart and I'd like to not be told that I'm young there are plenty of girls my age to date. I earnestly want to be with her and the idea of even talking to other girls is something I can't stomach right now.

TLDR: My girlfriend told me she didn't see a future and that we'd be better off as friends even though she had never brought this up with me before. I really want to be with her but I also want to respect her decision and don't know what to do.
