I get along with the girl at my work quite well and I've known her for some time too. Suddenly she has been quiter with me. I feel like she is nervous around me. I've noticed her blushing once, has offered to help me etc. Recently when I see her and say hello I feel as though she doesn't want to talk to me or it feels kinda awkward. Twice now this has happened. So I'll break the ice cause she hasn't come up to me. Next thing she is coming over to me and starting conversation after this slight awkward hello. Like when we do talk though it's always a great conversation, plus I get her to giggle too.
