Potential Suitors in 2018

Hello. My sister's date of birth is October 18, 1979 at 1:00pm, Toronto, Ontario, Canada. I am very concerned about her on/off relationship with her current boyfriend (a dragon). They were dating normally for a few months until one day, something snapped and he became moody, quiet, and then finally told my sister to "walk away" from him. I believe that his sudden change in behaviour was influenced by his parents, who disapprove of my sister even though she did nothing wrong. My sister is aware that their relationship will eventually fizzle out. However, she is having a hard time letting him go. This has been going on for nearly 2 years. Can you please advise whether you see any potential suitors for my sister in 2018 or even in 2019? Thank you so much for your guidance.
