Just some thoughts I'm having this morning
Don't make excuses for people who treat you badly by saying "that's just who they are, I don't want them to have to change for me" - you're giving them a free pass to keep being lazy and avoid self-improvement.
If "that's just who they are" then fine - "who they are" is someone who treats you badly, and that's not okay. "Who they are" is someone with different priorities than you in a relationship, and that's not okay for you. "Who they are" is not a good match for who you are.
Having negative traits doesn't make someone a bad person. But a pattern of negative behavior with no attempt at progress does.
When you feel like a need isn't being met for you in a relationship, the other person doesn't get to decide if it's a valid need or not. Additionally, don't convince yourself your needs aren't valid just because you think you are pleasing the other person.
