In 2015, Sunmi was announced to be resuming promotion with the Wonder Girls until their disbandment in 2017.
Over a year after I ended one relationship, I found some photos on Facebook of my ex with a woman I didn't recognize. (Sure, she exclusive and hadn't spoken in six months! After doing some soul searching, I realized my reasons were different for each person.
After a three-year long hiatus from the music scene, Sunmi resumed her career as a soloist in August 2013 with her debut extended play Full Moon.
The EP spawned the single "24 Hours", which charted at number two on South Korea's Gaon Digital Chart.
A friend once told me his test of whether he's over an ex is whether it would bother him if they were dating someone else.
Under that logic, I've never gotten over anyone in my life. After I last spoke to another fling I never even officially dated, I made sure to unfollow him on Facebook so I didn't have a similar experience.
The fact that you broke up wasn't a failure on your part; things just didn't work out, and they might not work out with this new person either. People don't choose people based on checklists; each person will appeal to someone for a different reason. Your ex's new significant other is not your replacement.
