I truly believe when your partner breaks up with yu, not a lot of people are truly upset about losing the person they think they love. They are only afraid of losing their routine. When yu lose your routine, and especially when it wasn't yu who made that decision for change, yu then fear not being in control. Most people are just upset over how their lives are going to change. When YU break up with someone, obviously yu will feel in control. And yu will feel yu're the alpha and the omega in the situation. But when SOMEONE breaks up with yu and the situation is reversed, yu'll feel real shitty as if yu've lost your domination in the ordeal. It's human to fear inevitable routine change. But as long as yu're in control of YOURSELF, things are going to be ok. Just remember, everybody fears not being in control.
