<human>: Could you distill the essence of the text into 1-3 sentences?

Me: 25/m. got dumped by fiancée (of 4 years) 6 months ago and coping well. Totally lost my touch and sense of orientation in the dating game. I'm average overall.

She: 25/f. broke up with her long term boyfriend a few weeks ago (no details on the break up) and emo-ing at the moment. My ex and her were friends as well as we came from the same school back then. She is attractive actually. I have no idea what are her character and personality actually. But from our experience back in school a decade ago, I would not mind dating her really.

We were schoolmates about 10 years ago and have existed as facebook friend till now. No meet ups.

She chat me up one day on facebook as she was feeling bored. So, the conversation progress to the point she said she need some distractions to cope with the breakup and I (randomly) said if I could date her out. Well, she agrees and she said if I am okay with her possibility dating other guys as well. 

Okay, here comes the tricky part. She is in a shitty and emotional state which most of you guys will tell me to stay out of it and not waste my time on it. However, I am a firm believer of fate and since opportunity present itself, why not give it a shot? My intentions are to understand her more, help her getting out her emotional shit hole and maybe if possible win her heart over. So woman of reddit, how and what should I do or not do and what else to take note of so as not to be insensitive to her situation plus not ending up in the "bro-zone"? Even if we don't work out, at least I give it a shot.
<bot>: = me hooking with a cute girl who just broke up in a long relationship and need advise to help her get over it and win her heart as well.
