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

I ended things with my ex in January 2014 after a bad argument. I still felt things for her but at the time, I wasn't mature enough for our relationship (it was mostly her indecisiveness and my ability to get a bad attitude over small things). We continued to be friends and talked occasionally since but schedules kept us from trying to pursue dating again.  
  
On 6/15, my best friend got in a horrible car accident and has been in the hospital ever since. She showed up at the hospital out of concern. She has continued to show up as well. Everyone around sees how we work so well together and they have been talking to me about dating her again. I am clueless to the signs that they all see that suggest that she is into me still but I trust all of their opinions on the subject.   
  
Now on to the problem. She is in a relationship with a guy she has been dating for 2 weeks. I am avidly against cheating. I can't be a part of it at all (not the one being cheated on, not the cheater, or the person that the person was cheating with). She admits that the guy isn't who she thought he was when they were "talking" and their relationship is strained but she hasn't pulled the trigger on ending their relationship. I have some friends (of their own free will) going to ask her tonight what is going on with that.  
We have had dinner multiple times since last week, including one with my parents. We have shopped together and spent a lot of time on the phone as well. We have even made plans to bake together tonight and go bowling Friday night. All plans of which she hasn't mentioned her current boyfriend going along with and I doubt mentioned to him either.  
  
So my question is: What exactly should my next move be? I've never been in this situation before and I feel a strong connection between us but I don't want to be the reason she cheats and I don't want to feel like the second choice because she hasn't ended things officially with her current boyfriend.
<bot>: I have feelings for my ex and I think she does too, but she hasn't ended it with her current boyfriend.
