<human>: Can you succinctly summarize the text in 1-3 sentences?

We met at my work place and hit it off really well, and she had recently broken up with her ex. 3 months go by and we are having the times of our lives- i couldnt have been happier. We had planned Halloween, Thanksgiving, Christmas, Spring Break together and it looked like that this relationship might last. Then in a 2 day period, she chose to be with her Ex over me. She told me she loved me, gave me some christmas gifts she had purchased for me, and then said that we were taking a break while she was with her Ex.

Now, 3 days later, she is still sending me good morning and good night texts, asking how i am doing, writing me notes; general stuff that a GIRLFRIEND would do. And i just want to try to move on, but she asked me to wait for her while she was with her Ex, so when they inevitably break up, she can come back to me.

I don't know what to do. I want to be there for her because I can tell she is hurt and confused, but trying to be her friend right now is killing me. Also, I dont want to "wait" for her to be done with her Ex, I couldn't stand being alone while she is off being happy, or just the thought that she expects me to remain loyal to her as she sleeps around.
<bot>: Ex Girfriend left me for her Ex, expects me to wait for her, but be strangely close friends in the mean time. I just need opinions on what to do; I'm Lost.
