Whats the best choice?

Well my girlfriend just graduated and i was suppose to graduate with her also but I'm a little behind and now she's finna go off to college and she wants me to move down there with her and its like three ours away from me and I want to move but i also need to finish school so should i drop out and go to faith academy which is an accredited high school also but the difference is you have the benefits of being at home and also perusing your diploma but the twist is that i want to go into the marines and a marine recruiter said they treat faith academy diplomas as a GED and i would have to have college credits in order to get in the marines with a faith academy diploma and me and my girlfriend never really get any time to see each other because her mom doesn't like me and doesn't allow her to see me or talk to me so we have to sneak around so if i move that means i would be able to be with her like we want too but i don't know if i should stay in regular school or drop out get in faith and move down to where her college is? And if i go with her it will take longer for me to get into the marines and go to college than it would if i stay in regular school....
