I Like Her But She’s In A Long Distance Relationship, Advice?

We are both in our first year of college, in different programs. We’re both 18, We’ve been hanging out alot lately, drinking and going to parties with friends and such. after the first/second week hanging out with her she added me on facebook and it says shes got a bf. before we started hanging out, her facebook status says stuff like “i miss my boyfriend” and stuff. It hasnt since. The strange thing is, she’s never mentioned, neither have her friends that she has a BF.
I know that long distance relationships dont work/wont work through the 3 years of college.. I feel bad and i don’t want to put her in a situation she has to deal with daily temptations.. I can tell shes really into me. If i make a move, and shes not interested in that way, theres a chance ill lose this friendship.
Should I just mask my feelings and remain friends until this relationship dissolves? Any advice or people that have had the same kind of problem?
