<human>: Can you condense the text into a few key points?

My ex-wife and I have been divorced for two years and we've maintained a really great co-parenting relationship. Other the last 3-4 months we've become closer platonic friends again, and have spent a lot of time with the kids together - even been on short vacations together. I've really enjoyed my time with her and now that all of the pressure and garbage from our previous relationship is gone and that we've both taken considerable time to work on our own issues - I'm seeing the person that I originally fell in love with again. I'm sort of crushing on her again. Gah. Sometimes I feel like there is something more there from her too.

I know it is bad form and not a good idea at all for us to get involved with each other. I know what a FWB arrangement would probably not be good for us either. But I can't help but have these feelings for her (emotionally and sexually). I don't know what to do. If I voice them to her, I risk losing the friendship that we've developed. If I don't, I continue on feeling this way with no way to express or get over it.

Do I act on these feelings in the hopes they are reciprocated? Do I distance myself from her? My kids are also a huge consideration and don't want to confuse them or put them thought anything.
<bot>: Sorta crushing on my ex. Not sure what to do, or what's best. Any advice/view points is greatly appreciated.
