If I were to sum this answer up in one sentence it would be this: practice directionalizing your thoughts toward introspection and prioritize considered response over reaction by asking more questions of yourself and others.
The first tangible example in this realm is knowing that the thoughts that you're having - while valid in your mind and, in fairness, maybe even valid in parts of reality - are more often than not at least partially inaccurate. Therefore, exercising your thoughts outside of a thought process will always be a mistake. This is analogous to jumping into a workout without warming up first. The mind should always be warm, like the body, to exercise what's in one's mind.
The 2nd example is knowing that you don't know everything regarding the situation of another person. There are pieces of information that you're missing now. When you eventually find them with time, you will be glad that you practiced restraint. More often than not, your initial thoughts and feelings will not be as meaningful as they felt in the moment and/or relative to the previously missing information.
The 3rd and most important is that no individual is worth controlling your mind to a point where action becomes the primary focus. Thought should always be the primary focus in order to make thoughtful decisions regarding one's own well-being. Consciously burning a bridge in any case is a sign of loss of control in one's thought process. This has occurred many times throughout my life, which makes me the complete opposite of an authority in most areas. But, like you, my spirit is strong. I work every single day to leverage the spirit I was born with to not just control actions that are not helpful to myself or my family but to protect my own well-being in order to set an example for those that need an example.
We are all capable of setting this example so I would strongly suggest that after reading these 3 actionable, detailed, direction-filled examples I've provided that you use your strong spirit to resist and exercise restraint. Set that example for those that need one (because there's always someone that needs an example) as opposed to having to burn the bridge. In my experience as well as my failures, I've learned that when something is true there is no need for a fight. There is only a need for restraint until there is a resolution. I learned this from the example set by my father and mother. In both their regards I've seen a lot of bridges that they could've burned but they were self-aware enough to know that those bridges would burn themselves so long as they exercised restraint. They modeled personal energy conservation for me by not expending their energy on situations that would ultimately resolve themselves if they simply chose to remain neutral and unengaged. Usually, fire starters have an inferiority complex. That's why they're starting problems with you. They're typically lacking self-belief which is a telltale sign of their destiny. They're going to burn their own bridges so you don't need to. The most appropriate response is always restraint.
