Ist love or lust?

okay she was always sweet to me and helpful anytime I needed her she was there for me when I lost many things she didn't give up on me I never felt anything to her till last few weeks we were in burger king and sitting together I was making eye contact but she suddenly couldn't do it as always , she was kinda avoiding eye contact with shyness.
Week ago she told me she will leave the town for about 2 month I felt very bad I admit I got teary eyes after the call I never felt like that for her I'm not sure if I fell in love with her or it's just lust. I will meet her again in a week before she leaves. I'm afraid to admit I love her and I'm not sure if it's love or lust.
What you all think about it?
