What would you do if you were me???! Helpp?

So my ex and I dated for 15 months and recently just broke up. Things were great for the first year. We get along so well, have so much fun together, and are head over heels for each other. A couple months ago we started bickering every now and then at each other. We got in more and more fights. She went away for a week on vacation and while on the trip she told me she had to think about whats best for us. This hit me because being separated with her was the last thing that I wanted. So I decided to get my act together. I realized I've been treating her poorly and focused on how to be the guy I want to be. Since coming back from that trip, things weren't the same and I could just tell. As hard as I was trying to make it work, it just felt like it was too late and she had already made up her mind. I approached her about it and needed to know what was going on in her head. She told me she had no idea what to do or what she wanted. She knows she loves me and wants to be with me but wants to get her priorities straightened out and is trying to listen to God and be with Him for a while before she can give everything to me. Trying to be as mature as possible, I told her I completely understood and want her to figure herself out just as I need to as well. But I don't know where this leaves us now. I told her time and space away from each other is probably whats best for now in order to give us the best chance of being together later. I don't want this of course but told her anyway. I'm so confused on how to approach this whole situation. I feel heartbroken knowing that we're in love with each other but can't be with each other at the moment. Any advice or wisdom would be really appreciated.
