For me, this comes down to accepting I really can't control what other people do. I can tell them what I want or need, hope that they're able to give me what I want or need and decide what's open to negotiation. So, I can ask plainly for what I want, accept what the other person can offer me or decide to go elsewhere . It's also about accepting that it's ok if people aren't able to or don't want to meet my needs or give me what I want - I can then decide from there where my limits are.
So, I can tell my hubby I want him to put his laundry in the basket and appreciate it when he does that. When he doesn't do it I can choose to get pissed off with him and pick a fight, do it for him and be gracious, do it for him and be a bitch about it, leave his stuff where it lies etc etc. Manipulation is at play when I respond in a way that tries to trick or manoeuvre him into putting the laundry in the basket rather than plainly saying why it annoys me and asking him to change, and accepting he might not. Ultimately I can decide whether I want to live with someone who is so messy or not.
It's a fairly minor example, and an area I struggle lots with, but it might help?
