I'm sorry for all of the pain that i caused you. I wish that I could have you I just wish that i could make you happy. I don't want to have my cake and eat it to

I am falling for a girl that is in love with me. SO what do i do, do i stay with the girl that i have been with for over 2 years or do i go for the girl that is like me and understands what i am going trough. After all the this pain i have decided to take a break from my fiancee. And try a relationship with a new woman, the one that seems to understand me more.
