<human>: Updated. 

In advance, I'm really sorry for all guys who advised me that I should move on and better off alone. Because within 2 days, I have had really huge alcohol and tried to contact my ex. 

Now I'm getting to realize that my ex girlfriend have never considered me as her genuine boyfriend but just DATING partner. 
Actually in Korea, there is no concepts for DATING, if you regularly meet someone and have deep physical contacts, then it must be considered as being in a relationship. 
Now I'm thinking even she is living in Korea, but she just wanted to meet some guys fairly like she is living in her own country. So it means she is really good at using the crosspath between the culture of Korea and America. For making the dating partner relieved, she just has said like "I love you and we're in a relationship blahblah.." even she has never wanted to be in a serious and exclusive relationship.
So I was NOTHING for her. But just dating partner.

Unfortunately I tried to contact her by Facebook which was the last string to contact her I had. I told her like "Just tell me the truth for the last time" but no responses. I felt really heart-broken. 
I know this is totally over. But now I feel really stupid because once if she come to me again, I'll totally forgive her and take her back. 

Actually I had never been in a relationship for last 8 years. Because my ex girlfriend who was not my recent girlfriend cheated on me as well. For 8 years honestly there were many girls who wanted to date or be in a relationship with me. But I had had a really serious trust issue to be in a relationship with any women. But finally I met my ex girlfriend and fell in a love. But as you guys know already, I'm heart-broken severely again..

Now I don't have any idea to meet any women again... I'm definately lost now..

"They say time flies but you keep breaking its wings"

Give me the gist of the text in a nutshell
<bot>: even I know this relationship is totally over. But if my ex girlfriend who cheated on me and kept lying come to me, I'll forgive her and take her back. What should I do? I don't know what to do.
