Can I be love with a woman who's engaged?
Are you serious because what is so special about this woman?
We were dating each other before she got engaged.
If she's engaged then you should move on. She is about to be married so there wouldn't be a chance for you to date her again.
What is so wrong with still trying?
It's wrong to try because she has decided to move on and love someone else, so why would you want to waste your time on loving someone who will not love you back? Also, you will get a bad reputation as a so-called home wrecker, and I know you don't want to get labeled as such.
