I'm dating a 19 year old...

Abi
A month ago, my boyfriend and I mutually broke up. We barely seen each other, so we thought it was for the best. Now, a month later, I miss him, and I want him back. The situation is he's 19 and I'm 15. If we do get back together, I can't tell my parents I'm dating a 19 year old. I'm so confused with life...
