Do you believe in fate?

When I met my former boyfriend years ago I used to see him around town alot before ever formerly meeting him. A year later he introduced himself to me and he asked me to be his girlfriend. I agreed because I just could quite understand what it was about him that felt so... familiar. 

We dated for about 2 years before he broke it off with me. We had a good relationship before the break up but we lived in different cities so he left me for someone who lived in his town, which ofcourse was shortlived and within 2 months he reached out asking to get back together. 

Like any normal person I burst out in laughter because to be fair there was no real reason that called for a break up between us, and he just didn't want to work things out he was so set on leaving me. 

My heart wanted to agree so bad, but logic disagreed, it made no sense, he begged to see me for weeks but I still haven't seen him, I was just so skeptical of him. 

What would you have done in my shoes? Would you have taken him back? Or would you have let dead dogs lie?
