This journey is indeed rough. It can feel like you're going crazy at times. Especially when the other person doesn't return the feelings. It is a very lonely situation to be in and it's unfair. It's feels unfair because it feels like you don't have any freewill in this thing while the other person seems to have all the free will in the world. People keep telling you that you have to move on and you know it feels impossible. Nobody understands. The lessons aren't being learned because they're exercising they're freewill to not learn them or to stay in relationships or situations they know is not making them happy out of fear. Fear is the common denominator in all this. Fear of getting hurt. Fear of letting go. It sucks.
