Intention in Relationships

I’m curious about how intention works in regards to relationships. Can my intention for my son to be better behaved or for my boyfriend and I to have more intimacy be done through non local interference? Can I have intentions to free others from addictions or for them to be more spiritually enlightened? I want to understand to what degree I am responsible for my own life and to what degree my intentions can make big differences in other people’s lives since we are really only one. Thanks!
