Omg!!! Long lost love

Katie
So when I was in 4th grade I had a bf and I know we were in love. Not like puppy love we were in love. Well one day his step mom and dad fought and he moved with his dad and never herd from him again. Well iwas on m y fb going threw my recommend friends wich I never do and found him and it was him! I'm now 6 weeks with my fiancées #5 and don't know what to do. Should I catch up or leave it be incase it ends up like the movie where she leaves her rich fiancée for her past love
