It's sad to me to read what appears to be you giving up on this person but planning to string her along for your own reasons for the next number of months.
Yes, she's damaged and no you're not a knight in shining armour there to rescue her. From what I read though, she's clinging to you and really wants to make this work despite the difference in age, the geographical challenges, challenges with her kids etc.
Perhaps I'm painting this with the brush of my own potentially budding relationship - there are always similarities if you look for them. My lady-friend is going through probably the second worst part of her divorce process right now.
Is this the "right" relationship for you long term? I have no clue. I don't know you. I don't know her. What I do read though is that she needs quite a bit of patience and a lack of pressure go get through this. If you are willing.
None of this stuff is easy. Especially the second (or subsequent) go-around.
