Sorry Guys I neet to Vent my Girlfriend Problems

I'm gonna be honest. I prob wouldn't feel too comfortable with my 16 yr old daughter dating an 18 yr old regardless of the maturity level. I sure as hell ain't letting her hop in a car and go for a ride 45 minutes away. Parents are very protective of their little girls. Either deal with what they let you do or leave cause they have every right to raise their girl how they want as long as she is under their roof and until she is of LEGAL age! Your just lucky you haven't been met with a shotgun!
And both of them have mentioned shotguns. Her mom even said if she doesn't come back from prom as pristine as she left that I'd be castrated, but truth is I don't care. Guns don't scare and neither does a missing nutsack. What scares me is life without her. Becasue on our better days, when her parents aren't tearing me apart, she is the only thing I really truly have that makes life worth living.
