<human>: Can you provide a brief overview of the text?

Hi all --

It's been a while since I've posted about this particular issue and this is pretty much the only thing that makes me befuddled enough to post online asking for some help and advice, so here I am..

My ex-gf and I, who I've known for over 10 years, broke up in July, but continued talking and hooking up through November, until we just drifted away. We broke up due to me lying to her and her feeling like she already wasn't getting enough from me, this pushed her to the point of no return. Through July - November, she kept telling me she was figuring out whether she could get over what I did, and being the smitten, in love person I was / maybe still am, I went with it. Looking back, I handled the situation with no tact and totally led to my own demise by being a pushover yet also an ass at the same time. Lesson learned, hopefully. 

So here we are today, we started talking about a month ago, she dated someone in between, it didn't go well, and now she's just down on her luck with guys, etc etc and I totally don't like to see her that way. We decided to go to a sports event on Valentines day since it was something we both were interested in and that went well. At this point, it seems strictly platonic, with her suggesting different girls I should get with, but I get the sense that there might be more. 

Her birthday is tomorrow, and she has a party she invited me to on Friday, but should I do something nice beyond what's expected? I feel like for so long, I was at her disposal, so that's not the right way to go.

At this point, I'm confused as hell. Do I want her? Does she want me? Am I able to be a platonic friend to her?  Am I just a stop gap for her right now because she feels down on her luck?
<bot>: Ex-gf has come back into my life as a platonic friend (seemingly) and I'm unsure whether I want her as a platonic friend and if not, should I make a move?
