I constantly burn all of my bridges.
What are you doing to burn bridges?
I want to tell my former girlfriend I don't want to see her ever again.
Don't be so decisive and demonstrative about people. Word gets around quick, try and be nicer to people.
I just really want my bridges to stop burning.
If you put in the work you can repair them. Go to the people in your past and tell them you are sorry about what you said to them.
