So at uni, in the library. THis girl looked like my ex, i hvae such storng feeling for her and i dont even know why. Well i do, because she looks like my obv but anyway. Whenever i see her i get nervous and look down, shes now also doing the same. I smile one time while walking past, now she does the same. I saw her with a guy but i dont know if they're dating. She tries to find me sometimes in the library. I dont know whether shes interested in me or just curious why this random guy keeps looking at her and smiling and being nervous. Thoughts?
What should I do?
