Absolute best ways to get over a break up?

Hi ladies! Hope you're all doing well tonight. I really want to know how you personally get over break ups. This isn't my first rodeo, but this time is hurting especially bad. He was my best friend turned boyfriend and now I feel as though we're forced acquaintances, we can barely talk to each other. There's no bad blood, just changed status. Any words of wisdom on how to heal a broken heart, but keep the person who broke it in your life? Thank you 😃
