<human>: Condense the text into a few key points

Okay, so bear with me this is my first time posting on Reddit. I apologize for any mistakes  with titles or format.

I'm not sure how to start this. I guess some background information. I met, Sarah 4 months after getting out of a 2-year relationship and pretty much fell for her immediately. Oddly she had just got out of a 2-year relationship as well at about the same time. She was funny, beautiful, and fun to be around we quickly became  best friends. Nothing about the relationship felt off (ever). There was never a second I didn't want to spend with her the sex was the best I've ever had and I've never been that comfortable around someone in my life. She felt the same. We even talked about kids, houses, marriage  and were looking at apartments. She told me she's never been this happy and never loved someone like she loves me and I believed it because I felt the same way.

So cut to last night, after about 30 hours of her not responding to any messages or phone calls I gave her, which is completely odd and I was worried. We've talked everyday for 8 months non stop. Out of no where she breaks up with me over the phone when I live 10 minutes away. When she was talking to me I could barely speak trying to catch my breath, crying and wondering where the hell is this coming from? She was, stoic? Kind of a monotone voice. No quivering, no hints of sadness and no crying. She said this was because she had spent the last 2 days already crying and even throwing up.  Her reasoning for the break up was: She needs time for herself right now. Literally, a day before we were all cuddled up on the bed watching Netflix and she told me she loved me more anything and then boom, this.

Was this a rebound? I've never felt like this about someone and I'm having a hard time believing I'll ever feel this way again. I'm more messed up than I was after getting out of that 2-year relationship. I just need some help understanding this and have no one I can really talk to.
