Love is not possession. Being obsessed or trying to control what people do is not love. The constant need to control other people is a representation a lack of control you have in your own life. To love and care for someone is to give them the freedom to do whatever
Just like “what one person won’t do, another one will”…what one person won’t tolerate, another one will. Don’t ever regret walking away from a situation that didn’t serve you. People don’t change overnight, they only change the people that don’t see the flaws in them (yet).
