sweetie I have to give you credit...I am very glad that I am not 18 anymore because it is a hard age to be.
I know that this probably won't help but what you are going through is normal. The problem with guys who are 18ish or so is their maturity. 18 year old girls usually are able to handle a deepr level of commitment then an 18 year old guy. Hell I'll tell you a secret I know guys in their 30's that still cannot handle commitments. In other words what you want/expect out of this relationship is probably not what he wants or expects.
I know that this does not make it any easier but you are not alone. Tons of women struggle with the same issue that you are dealing with everday.
Just remember sweetie relationships can change and come and go but there is someone out there who is right for you. If you don't feel like your needs are being met then don't settle. You deserve to be happy even if it is not with your current boyfriend.
I have been in your exact place and I strongly feel that everything happens for a reason.

Stay strong,
Jessica

You are in this snowglobe. It is encovered in glass and secure. But one day someone comes and shakes the globe and the pieces go flying everywhere. Now they will eventually settle but they won't be the way they were before and they can never be that way again.
