It's natural after a period of calming down, to think of the good times, great memories when everything was fine. Conveniently forgetting the behaviours, the stress, the confusion, the sick feeling in the pit of your stomach, the times you couldn't sleep after a row when you knew things were going wrong....etc.
However ignore this as your peril because all you do is delay the healing process, and feel undignified/upset if the other party does not want to reconnect...and you have to start all over again to recover, to regain your self esteem and autonomy.
Alternatively you both get back together and everything is great for a while...until the reality, the personalities, the issues, the annoyances and differences come back in which they inevitably will. Honeymoons don't last.
I've done it myself a long time ago, it lasted about a week. Sometimes love isn't enough. I still love my exH, doesn't mean we could ever make it work again.
Am staying away from someone myself at the moment, someone who gets off on mind games and feeling superior....I will not feed their ego. I remember many good days and times, but also being ground down and manipulated. I'm doing fine and won't let go of the feeling of peace, relaxation and the lack of stress that I've found. Just moving on when I'm ready...on my own.
Time to be honest with ourselves, face reality and say a sad goodbye. Just my humble opinion.
