<human>: Met a girl last Saturday through two of my best friends (who are currently dating and just left to go to Europe for August). We really hit it off, and at the end of the night I asked for her number. She said something to the tune of "not right now" and left. I thought this was odd because of how well we were getting along, but respected it and let it be.

A few hours later I got a text from her (she got my number from one of our mutual friends) saying that she had a lot of fun tonight and that she was sorry about the number thing -- she was in a complicated situation and trying to get over someone, and that for some reason it was making her apprehensive.

In my response I explain my situation -- I just got out of a 3+ year relationship, and while I too am a little wary of starting anything with anybody, I had just wanted to talk again and get to know her a little better (to me a phone number didn't seem like such a big deal, but I don't know her circumstances and I didn't want to pry). She says that she should have herself sorted out closer to the end of the summer and could we talk more then? I didn't so much agree to this as I said something to the tune of 'you need to do what's right for you, you have my number'. 

So, the problem is that while I should just be moving on and letting this be, she really made an impression on me. I want to respect what she wants, but I also really want to talk to her. I don't like these situations where I feel like I have no control. Furthermore, since our mutual friends have taken off to Europe, there's no way to hang out with her without the two of us directly contacting one another.

My concern is that by the time a couple of weeks roll by, she'll have forgotten about me. I want to prevent this, but don't know how given the limitations placed. What should I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Hit it off with a girl, she's just gotten out of a relationship and wants to wait to get to know one another a little better. Don't want her to lose interest in that stretch of time -- what to do?
