Please help me with my English..

Even though my love story is poor (-->This doesn't sound very natural in English.  It might be better to say something like "Even though my heart is broken"), I will not give up hope. It's not wasn't just once that you've hurt my heart. me, but it was the first time I my self witness saw it with my own eyes.

Thanks

Ouch. That's sad. But pretty good writing. For more natural style, I would write it like this. 

The story of my love is sad, but I will not give up hope. You've broken my heart more than once, but this is the first time I saw it with my own two eyes.
