How can I better deal with conflicts in which ego is involved?

Usually when someone pushes back against me, I feel displeasure, and I am very reactive. I say something defensive in response, but then, I yield entirely from the subject or area in which I was pushed back against. My ego tries to frame this yielding as being egoless, but obviously, it is just to protect the ego. How can I remain in such a conflict of interest without either yielding, or letting my ego influence the conflict? For example, if at work, my ego has attached itself to some submission, and someone points out things they feel are worthy of change in the submission. How can I remain objective, without jumping the gun (applying the suggested changes immediately, or rejecting it outright, or yielding from the submission entirely)? When I happen upon a pushback, the first few moments are of clarity. "Oh, I see, interesting". But then slowly it irks me and I become rejective. Then, after I push back, I go "this is too much, how will people perceive me after I pushed back, I'm so confrontational, I gotta leave/yield".
