A good remedy for a broken heart is time. This is a duration in which one should have before he/she engages in a new relationship. Others include spending much time with friends to avoid remembering your past and watching movies. You need also to accept that you have been hurt and accept that you need to move on.
Music. I GUARANTEE you will find a song you will relate to! Music has always been there for me, even when people haven't. I guess it's knowing that there are enough people that have gone through the same thing that they can write a song about it is really comforting to me.
Music, ice cream, movies and spending time with friends and family are always great. Go out and have a fun night with your friends and take your mind off things! Also, if your okay to look back at the relationship, focus on the negative things to help you move on. Also, time will heal a broken heart. don't feel like you need to rush into another relationship right away. Take time to forgive(if you can) and forget. hope I helped :)
