So.. At the age of 15 and 16 we met through a mutual friend, we met up, like each other a hell of a lot and ended up with me getting pregnant at just 16 
We had our son and everything was bliss... Until he was cheating etc and we parted ways. After 9 months apart and seeing other people we decided to give things another go for our son... But we were still only 19 and 20 and broke up. After that time I moved away... He got into trouble. But now we are 26 and 27. We have spent a lot of time together over the last couple of years, even with our new partners, but now we are both single and leaning on each other once again for company and support. We have always got on like a house in fire.. And now everyone around us asks why we haven't questioned giving things one last try. He seems to have matured.. He seems a lot more sensible... But is this just a front?I was really against it due to the fact I'd been so heartbroken in the past.. But now I'm sat on the Internet asking you strangers for opinions in what I should do 
haha. So... Can after 10+ years of being apart.. Can you start to redate your childhood sweet heart whom you share a child with? Or is it best left as a great friendship/Co-parentship
