You want you're cake and eat it too.
you can't have it both ways.....not fair to her, not good for you (You know you're not doing the right thing).
Here is the thing. At 19, you have absolutely no concept of time.....you've only been aware for what 14 years or so....that' nothing. Everything seems like it's the most important thing in your life. What is the life expectancy of someone who is 19 today.....85 or so? that means you still have 66 years to go.
Flip makes some good points about the benefits of being in a meaningful relationship compared to a meaningless one.....problem is, you're still only 19.......you will do more growing and learning about yourself and changing in the next 7 years than you have so far (IMO, in terms of maturing). You have much to learn. You may not be capable (nor may she) of a meaningful relationship.
So here is my advice FWIW, knowing that I don't know the first thing about you or this girl. Take it easy......it's not necessarily an all or nothing proposition.....talk to her, tell her honestly what your conflict is......tell her what you want and what you need.......Trust her to take care of herself......be honest with both yourself & her about where you are in your life......if you want to date non-exclusively, tell her......you risk that not being OK with her, but wouldn't you rather know that now?
But you have to decide for you what you need, what you want, before you talk to her......it's only fair to her......worst thing you can do is tell her one thing and feel another...that leads to resentment.
Good Luck.
