Buddy im glad that i've managed to be the first to post on this question. I can totally relate to your situation as i am currently, finally dating a woman who i met through very similar circumstances. The only really difference is that she has two kids and i closed after around a month. Now the advice i'm giving you isn't full proof and ill never pretend im a PUA god but i notice a few similarities between your current situation and my present one.
Firstly what screams at me from your post is that you believe deep down that you are a good match for her and that despite all of your unsure questioning beliefs that you really dig her. Thats kl, embrace it, don't get too caught up in gaming her. You have obviously developed natural qualities that she is into and she is (
From What I've Read) treading very carefully to make sure that you aint going to hurt her.
Secondly, yea her situation sucks but, everyone has baggage. You could find a 21year old chick with hundreds of the shit and a 40 year old with very little (Although thats very very unlikely

)
The one thing i want to ask that i didn't really get from your piece was what do you want from her? You chatted a lot about what she is looking for in YOU but not what you are looking to get out of your situation? Are you wanting a little bit of fun or are you looking to win the game with this one?
