Love...what is that?

Its been 8 months into the relationship and I dont know what love is. I tell him I love him in response to his I LOVE YOU's. I get butterflies when I think of the three days I spent with him...I get all happy when I see a picture of the two of us. I get warm and bubbly when I remember his kisses and how he whispered in my ear I love you. I love it when he sings and sang to my ear all those songs that he once sent me through FB messages.

Is that love?
How do I know if he loves me?

He had thoughts of coming to visit me...but he cant get a visa unless he has a stable job or if he marries a US citizen. But im not ready for marriage...because I have 3 yrs of college left and if I did get married my financial aid could be affected.

So what do I do? Not sure.

Im so confused.

Its either I give this love some more time or do I break it off? I feel great when im with him...when its just the two of us. I feel comfortable...I can be myself with no problem. But im still young...maybe i'll let destiny take its course.
