How do I make this work?

It was all going well with my girlfriend until we ended this semester (we are both in college) now we are at home for summer nd d relationship has lost its spark.I can't go see her cuz her parents are quite protective,her location is quite distant plus I don't really have much money to take her to have a good time,I don't like telling her I don't have money («but scratch dis, it doesn't rilly matter)how do I up the ante nd re kindle this relationship.she's 17 I'm 20 cause even when I call she does must of the talking,I want to talk more connect with her more,make her laugh.I talk to some girls though nd sometimes I know what to say but with her (my gf) I just kinda blank out.I don't think this is normal,I rilly love her nd I don't want our relationship too die :(...so what d problem ?,how do I solve this problem,is it me ?it your say...thank you
