A guy with questions here!

Hello everyone, I´m Alex and I´m from a beautiful place called Playa del Carmen where I´ve lived for almost 20 years. The reason why I subscribed to this forum is because an experience I cannot quite figure out, like millions of other experiences around the world everyday except that now we have these forums, so we can get and provide significant help.
Anyway, I hope anyone here (specially a woman) has the time to read my story and to help me with some clues. It´s about how someone can be so happy and willing to change her life and then, in a wink of the eye, to go completely amnesic (maybe that was the reason!!).

Thank you and cheers!
P.s. the name of my story thread is "I didn´t have closure".
