I'm not sure that there will ever be a clear cut answer to your question, everybody handles things so different. If you're completely 100% positive that it's over between you and her then the one thing you can do as bad as it hurts is just make sure you're dealing with how you really feel and working through it. Let yourself hurt for a little while.
I don't necessarily think it's healthy to try and jump right into another relationship until you are sure you're ready for one. It's not really fair to the person you might be jumping into it with also, not to mention yourself. For me as petty as it sounds too, if I try to remember why we ended it in the first.
I try to focus on reasons that we aren't together and things that I found fault with with the other person. Sometimes when a relationship ends and you still have feelings for the other person you may try to romanticize the relationship, only remembering the good times you had with the person instead of seeing the relationship the way it truly was. I hope this maybe helps you a little bit, I'm sorry you're in that place at all.It's a tough spot to be in.
. This case is very sensitive.. breaking up with one you love is really a risk that you need to take especially when you know that she doesn't love you anymore. But in order for you to move on... you need to love someone else.
Its hard to manage but you need to do it if you really want to forget your past.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
