Is it wrong?

Some people have an amazing recovery rate from breakup (at least to me it's amazing). How does someone break their attachment to a person, a soul, a living thing and then move on to another person in months. Okay. I know a lot of you out there are probably like that, but seriously, how do you do it? How do you go from thinking about Person A day in and day out to thinking about Person B in a couple of months.
I always think breaking up is like detoxing yourself from that person. It's a process and it takes time. It's like a mourning process. You go from thinking about that person all the time, to just some of the time to maybe once in a while. Maybe other people are more flexible in their emotions or attachment than me. The amazing part isn't just getting over the person, but to move on and be willing to risk again and go out with another soul. How?!
Certain things bother me more than other. Well, i know, a lot of things bother me and bug me. But really, seeing people dating people who are either wrong for them or knowing that it won't work out and someone end up getting hurt. Maybe it's my intense desire to stay away from hurt and pain. I think pain in an inevitable part of life, but there are some pains that you are just asking for it. To me, that's STUPID. Well, there are some pains you want to endure because the end results is a positive one (like drawing blood, which to me is still one of the most terrifying things to do). Then there are pains that you can avoid but you don't. Actually, i am thinking more inflicting pains on others rather than yourself.
This is the part about relationships that bugs me. People date people, people date the wrong people, people let themselves fall in love with the wrong people, people allowing the other person to fall in love with them and then leaving them. Some scars last for life and it may make you a better person, but really, does that dismiss the fault of the person who inflicted the pain in the first place? Okay, this has nothing to do with me, but it just bugs me. It bugs me that people think having pure intention in the first place implies no guilt. Why can't people think before they act, well, i guess if people do that, we can probably save ourselves from a lot of mistakes. Ai. I am just picky. But really, what's a little more thinking ahead, and a little less regretting. Some mistakes are not reversible. You can always learn from your mistakes, but some, if not all of us had paid for mistakes that we wished we didn't make. Especially those that involve hurting another person's feelings. Okay, enough venting for the night.
P.S. this is not a personal issue at all, but just an issue that bugs me. I think if anything, i think a little too hard before i do anything, thus one of the many reasons why i am still single, and probably will stay as one.
