The chains of the past that bond us

It's been 2 years since I've seen Cole, the love of my life, and also the man that broke my heart. Since then I've been flooding my brain with my business, and keeping busy so I eventually ended Up forgetting about him. Until it was my best friend's 27th birthday, and she introduced me to her Fiancé Cole. Now I am torn on what to do since I haven't seen him in years. Even though I try My best to avoid him it's like that electric feeling between us won't go away. Should I tell my best friend about our past, or should I keep it a secret.
