In love, a sense of boundaries is very important. There is a famous hedgehog effect in psychology, which means that two hedgehogs want to hug each other for warmth in the cold winter, but they hurt each other. So do people. When two people get too close, they will lose their sense of boundaries, and their privacy and personal space will not be respected, which is not conducive to their respective development.
The communication between people needs to maintain a certain sense of boundary. No matter how close a couple is, they can't stick together all day. They need to rely on each other in scale. Simply put, the sense of boundary in love is not to rely too much on each other, please each other, and not to impose your own ideas on each other.
personal space
Couples need to leave some personal space for each other and learn to understand and accept when necessary, instead of forcing each other to stick to themselves all the time. Sense of boundary refers to the inner self-boundary between people, which is what we often call the bottom line or discretion. Kind of like a room door. If you lock it, others must get your permission to enter your room.
If you don't know how to maintain the border and always leave the door open, then others enter the room, even if you are angry, there is nothing you can do. From this perspective, people who don't know how to maintain the border will feel even worse when they are invaded. Because here, we first gave up our own boundaries.
