Based on the context of her text to the OM, I believe that she told him that she wants to cool things a bit while she considers what she wants to do.
Yeah, I was afraid of that, Sho. I'm so sorry, but I think in your gut you knew this was probably the case, didn't you?
Time to move forward with your life. Whether or not she changes course and decides to try and join you again is out of your control, and totally her call. I pray you will still have feelings for her when that day comes, and that you'll play your cards right at that key moment.
