Los Angeles: Singer Joe Jonas says he found it therapeutic to write songs on his breakup with former girlfriend and model Gigi Hadid. The “Cake by the ocean” hitmaker penned a number of tracks following his split from Hadid, but he doesn't plan to release the songs, reports femalefirst.co.uk. "Those songs in particular didn't make the album. You might hear them eventually, songs leak all the time, but I think the place I was in my life when I wrote them, I'm not there anymore, so it wouldn't make sense to release them,” The Sun newspaper quoted Jonas as saying. "I'm much happier than I was. They were reactive and therapeutic. You've got to let it all out and sometimes you have to step back and say, 'Is this me still to this day?' and you realise that you're in a different place,” the 27-year-old added.
