what to tell someone that went through a bad breakup

I'm so sorry to hear that you're going through this. Breakups are never easy, and it's completely normal to feel a range of emotions right now. Remember that it's okay to grieve the loss of the relationship and take as much time as you need to heal. Surround yourself with supportive friends and family, and consider seeking professional help if you're struggling to cope. Just know that you are not alone, and things will get better in time. You are strong and deserving of love and happiness.
