to tell you the truth, as Im learning and getting older I see that its never a good idea to make more hate and negativity come out of being hurt. at the least make sure that you arent becoming a hateful person. that road will only get you even more hate and scorn. its all going to come full circle and get back at you. its also a waste of future opportunities and time. youre shouldnt to let anger corrupt you and make you a weaker person. just be sharper. hold your head up. the next person you meet might actually be right for you, provided you dont play games and try to hurt her. even if shes not, you still need to have your senses on point and your mind in the right place. but you wont know whats really going on if you get stuck on that bullshyt. also, the next person might not deserve it and youre just adding onto the problem we are all facing out here. just be real and be you.
if you feel like you did something wrong in your behavior and need to correct it, then do that. anything more, like backtracking and rethinking things too heavy is unnecessary and a waste of your time.
as for you checking up on her and thinking about her, just forget it. its not even worth it. once its done, its done. dont let yourself fall for any of her games that can come from you being open. women can smell when you still want her and are leaving the door open for her. just cease and forget about her. for the most part shes moved on, so you need to also breh.
good luck.
