Mate I guess you feel the way you do because you still care. Sadly this stuff seems to take a while to work through. Some days are better than others. Perhaps you wanted your buddy to refute what you said. That way it would give you hope that if others think you and your ex are good together then maybe you are.
Have fun tonight with your mates.
As for day man it is draining. I am hoping my ex wants me back but in all reality I just do not know. I hope she is just not trying to be friends or any of that e. Still when I see her I am going to tell her how I feel and go from there.
