Sorry but this comment just straight urked me. She has two kids and she is not about to not take the relationship seriously. Her and her kids have already been through too much by not having a complete family so I doubt she is in it to just f*ck around. She needs and would want a responsible man who will not only be right for her, but a good influence on her kids.
No sir. There's no shortage of women that got married too young or too quickly that just want to sew some wild oats once they're free.
You are right. It is conceivable that she is just "DTF." However, I would argue that any woman who's focused on that without any regard of how it may impact her kids' emotional well-being (who have powerful intincts) then either a. she is not a good mother at all, b. not a woman attractive (prospectwise) for a man who can freely date a single woman without that level of drama, c. nor worth risking a broken heart if he DOES end up falling in love.
Given this point, I stand by my original opinion since I do not believe she falls into the DTF category.
No disrespect intended for Xak at all, I am thankful to be able to add my opinion here and wish you well with whatever you decide.
