My friend criticizes me on my relationship?

my boyfriend moved so now me and him are having a long distance relationship. My friend always asks me everyday if i am still dating him. I think she disapproves of our relationship, but im not sure. Sometimes i think she think that i am being a loser because i have a long distance relationship. He is coming back in 2 years so i dont see why i cant have a long distance relationship. What im asking is. Do you think maybe my friend is worried about me having a long distance relationship? or does she think that im stupid for staying with him after he moved?
