“The future influences the present just as much as the past.” Friedrich Nietzsche
You can try to make someone take the blame for your hardships in life but it will only put you in a worse predicament, it will only hurt the relationship you may be currently trying to establish, whether it be a significant other, friend, etc. You are after all the one in control of your relationship with the other person who is involved, to a certain degree of course. It’s no one else’s fault what you’ve gone through with others from your past. No one should be taking the blame for past occurrences, nor for the pain others have cost you. Instead you should be looking forward, and if you’ve decided that you can’t do that then you shouldn’t be dating. It’ll make everyone else’s life far less complicated and you’ll be doing yourself and the other person a HUGE favor. Your feelings of the past affect how you perceive the present, and if you can’t let that go, how will you move on?
