Wow I never realized how it can hurt the other party by not letting them in :/ I'm actually the kind that shuts people out but I do so because I don't think anyone really cares-- I mean I'm more aware now but I think it depends on experiences because if you've been let down your whole life, it's kinda hard to trust someone
I do that too. But it's not that anyone comes and asks if there's something wrong with me, so I generally just don't tell them. I do believe though that if someone cares they generally will ask you. If they don't ask you, it's no big deal to them, so no need to go on telling them about your problems. This can have the opposite effect on a lot of people, they grow tired of hearing problems.
We have to keep in mind that people have different coping mechanisms when they are faced with something difficult in their lives. Some people feel better by holding into people close to them, while others just need time to process and confront it on their own. Some people are introverts, some extroverts.
My opinion is that if someone needs time, the other person has to be understanding too. If they don't feel like opening up, the other party should not take it into heart so much. Just like how some people are more prone to jealousy, while others don't get jealous easily. Some people even want their partner to get jealous just to feel they care for them. others feel suffocated. Not everyone shows their love/emotions the same but I'm not talking about extreme situations though.
That being said, I also believe there are two types of shutting people off. The first is just being alone and trying to figure things out. The second is being a jerk/rude and lash out their anger on people who care about them. And this is the wrong type.
So, will Sung-Pyo or even No-Rae never find someone who can have a long term relationship with, just because they might have this habit? There is always a good match for everyone. Some people bring out different sides of yourself that others are not able to.
For example if someone else was in No-Rae's situation they might have handle it differently and not freak out. I'm not saying it's bad how she acted, but to me, they ultimately were not a good match. It seemed like they were good in their good times, but when a difficult time rised they fell apart. Being able to handle someone's bad sides is very important in a relationship, more important than the good times imo.
