You are allowed to wallow in your pity, if that's what you would like to do. Everyone needs a bubble bath, pail of ice cream, and case of chocolates, now and then.
I think that if you wake up tomorrow morning and think to yourself, "what the heck was I thinking, I need to let go of that conversation and continue moving forward with my life, with or without my SO and go to work and take care of business and not get sucked into other people's dramas"... then... I think you are well on your way to mending...
If you can't do that tomorrow morning, then maybe wait another day to respond... and maybe... you will be thinking the above on thursday morning.
