Dating in senior year of HS, but college is around the corner...?

Let me start of by giving relevant information.

I am a senior in High School

I am 18 years old

I have never had a girlfriend

The touch barrier has only been broken in the form of hugs (No kisses, yet)

As you have concluded from the above, I have never been intimate with anyone.

I BECOME VERY ATTACHED

Suffice it to say, I think I am falling for a girl in my school. We are both seniors. I want to ask this girl on a date, but there is a problem. While I do not fear, have anything against, or have problems with commitment, I will be in college in about 9 months. So will she

My problem/question is that if I enter into a relationship now, and it really hits off, I will either have to go through college with a long term relationship, unable to build a relationship with anyone else. Or, I will be forced to either break up, or have it be a short-term relationship. Again, I get very attached.

Just a note... I am okay for the relationship to not be intimate, but I still want it to be a relationship.

Any advice is greatly appreciated.
