Most Helpful Girl
When you enter into a relationship there needs to be sacrifice. Since you seem torn between having her in your life and the life you want for yourself , I think it's better off you stay single.
You may miss her but you need to take this time to enjoy who you are and the opportunities you may not have if involved with her.
When you enter into a relationship there's always rules and boundaries. Some of the things you now enjoy may have to stop because it won't be pleasing to her.
I suggest you enjoy your College experience.
When you are a little older and more mature , then partying , doing your own thing won't matter to you as much. You'll be ready for a girlfriend.
Keep her at arms length.
Let her know you still care... but mentally you are not ready.
Understand that is ok.
You need a time out for yourself.
