Trauma makes you tolerate a lot of mistreatment, disrespect, and shit you don't deserve. Healing makes you realize some people don't deserve to be in your life – no matter how much you love them.
You can tell a lot about a person by what they lack. Their lack of effort is their lack of interest in you. Their lack of interaction is their lack of resonance with you. Their lack of response is your lack of importance to them. See them as they are, not who you wish them to be.
