She recently broke up with this guy. They've been together for a soild 2-3 years, but she's left him multiple times, and they've been on and off for over 5 years, total. We're not currently dating or anything, but she knows I really like her. I couldn't be happier knowing she's now single, but deep down, I'm concerned I should be cautious. Is it common for people to date on & off, and break up with who they're with to go back to that person? If her and I dated, would it possible I could get left and she go back to him? Or maybe if we date, and I'm better than he was, she'll forget him? I understand if this question is too vague of details to answer. But considering she just went through a rough break up, leaving him, I feel it's very inappropriate right now  to talk to her about her previous boyfriends (or if I ever should).

If any of you have been in a similar situation as to mine, or been in her or his shoes, I'd love some help! Thank you...
