Turning our story into a book?

Sooooo my husband and I have been through a lot together and its really just like bad movie...
I'm actually a good writer I think and asked my husband if he'd think its okay and he thought its cool. Right now I'm just staying at home with the kids and I think a lot about our past so maybe writing sonething down could help me as well.
I'd probably change some parts I think so he wont go straight up to the jail if this would work out but I'm not sure if I should really do it? 
I thought maybe I could put it online on wattpad or something and I'd be really happy if some girls would read it and not end up doing the same shit that I did like as a warning sign for them.
