How could I hurt somebody I care about like that? Why did our relationship just fizzle out? Could I even imagine getting in a relationship with somebody else?

i understand the grief you may be going through right now. it is normal to feel this way after a breakup, so don't feel too bad about yourself. if it didnt end well maybe they weren't the one for you. there is someone better out there for you, you may not feel that way right now, you are probably still upset and angry right now but i promise one day you will be able to look back at this and appreciate this person. if you hurt them and truly feel sorry, a good idea would be to apologise to them. this way they would know how you feel.

It is very hard to believe that we could ever hurt the person we care about. However, I know that in some of my longest and closest relationships I have done exactly that. I believe that it is very true that we do indeed, Hurt the Ones we love the most. It is not that we mean to, but when you find yourself in an argument with your loved one and both of your are throwing darts at each other, it is unfortunately human nature sometimes, to aim and fire at the most vulnerable part of that person. In truth you do it because they have hurt you or you are even angry about something else and they are closest to you. The trouble is that as relationships continue over long periods of time, you can start take that person for granted and when that happens, you tend to lash out and say things and do things without considering how your partner feels. The trouble is at this point, if you don't wise up and learn to communicate with each other in a caring manner, even when arguing, you can and do finally say the one thing or do the one thing that the other person just can't forget or forgive and so the relationship dies out. Eventually, once the time for grieving the relationship is over, you do start to have a relationship with someone else and hopefully use the lessons learned in your previous relationship so the new one is successful.
