"If she fancies one guy but the other guy makes her feel secure about the future that's the one she'll go for!"
This is really it at the heart. They'll "settle" if another guy will be there for them, even if their feelings for him aren't as strong. Also, women always have options lined up. Even while she was with you, trying to make it work, she had another guy on the radar. She didn't just "jump" to the next guy. He was probably always right there. When women really want something, they'll do whatever they have to to get it. She wanted another baby, but wasn't sure you'd be there, that's why she stopped trying with you, even though you were still seeing each other.
My first cousin had this very thing happen to him. His employment was unsteady during his first marriage (he's a film maker, so he took whatever work in the business he could find, or even Starbucks, to keep money coming in), and the wife, though SHE had steady employment (worked for the Mayor's Office in LA), wasn't secure with him. She refused to have a child with him, or even fuck him at all for long stretches. Immediately after the divorce she had a kid with a random dude. She decided to essentially raise a kid alone than with a guy that loved her, but didn't make her feel secure.
