<human>: So about a year and a half ago me and my most recent ex broke up. I was very close to her and her children, she has 3, and I continue to be a part of their lives. I was crushed when we first broke up, and took some time away from seeing and talking to her, but then after a while we both decided that we could remain friends and that I could still be a part of her children's lives, which I am very happy with. Everything was alright for a while, I even stay at her place every few months to spend time with the kids. She does have a boyfriend at the momet, and we get along for the most part, though he isn't aware or my past with my ex. We both though it was best to just refer to me as a friend, which isn't lying but at the same time  isn't the entire truth.

Now the problems have started recently, I have found myself starting to fall for her again. I'm am currently staying with her though Thanksgiving and I'm finding it harder and harder to keep my feelings at bay Now she has dropped a few hints that she is beginning to feel the same way, telling me how much she loves and misses me, saying how sometimes she'll lay in bed with her boyfriend and wish it was me there, but nothing physical has happened yet. 

I don't want to lose her, or her children, but I'm afraid that if i peruse this and nothing comes of it that we won't be able to go back to being close friends a second time. Plus, the relationship that shes in now is pretty stable, money wise not emotionally, and I know that I won't be able to provide the same sort of support for her that he does at the moment. I just really need advice on what to do, should I sit her down adn talk to her about it and risk messing things up how they are now, should I just try to contain my feelings until I'm in a better place to provide for her, or should I just distance myself from the situation, and risk hurting her and the children, not to mention myself?

Could you distill the essence of the text into 1-3 sentences?
<bot>: I'm finding myself having feelings for a very close friends, and former girlfriend, and I'm not sure what to do.
