<human>: Can you condense the text into three sentences or less?

She's everything I want in a wife. But I'm still so young and I have so much life to live and our lives together as a couple are so vanilla and boring. I still feel like such a child and am not ready for seriousness.

She's the only person I've EVER dated long term, ever even considered.

I told her maybe we can get back together in a few years. I told her if she found someone else I would understand but it's all just too much for her to bear. She's completely cold and just hates me now.

I've really lost her and I just want to know what the gaps in my understanding are so I can empathize with her and learn. Because it's not because I don't love her I'm just not at that stage of my life.

If you could give me some tough love, maybe tell it from her side, the side(s) I'm not seeing.
<bot>: I love my girlfriend but I'm too young to settle into a serious LTR/eventual marriage and I'm devastated that it's over now. Can you pitch her side to me so I can empathize?
