About a month ago I stumbled on insta upon a girl that I graduated with about 3/4 years ago. Back then I just came to the country, was shy and very anti social. We used to have a class and she was always super nice to me and tried to interact with me more which made me feel good. She’s a very friendly person in general. When I found her I decided to DM her and talk with her a bit. She didn’t recognize me at first. We messaged each other a bit, with me being the force of interaction. At some point I asked her if she would want to hang out and catch up to which she replied that’s she’s busy. I took it as no interest and just shrugged it off telling her just let me know when you have free time. Couple days ago I was at some store and who happens to work there? That one girl. She approached me and was as friendly and nice as I remember. We talked shortly and then she said she is sorry that she never came back to me because she was busy. She mentioned it a couple times and said that we should hang out and she will let me know when she will be free. The next morning I messaged her a joke about her store and then said I’m gonna take her word to us hanging out to which she said that she’s just sainting for her schedule. We met up Mon, I messaged her Tue morning, and didn’t touch yet (Thur right now). Now i don’t want to be a nagger but at the same time I do think that I should message her to show interest. The thing is that she already “declined” once in my opinion and maybe her niceness is what brought up the subject again. She’s super cute and nice, and I can keep going on how much I respect her, at least from my memory of her. Just don’t know what to do. Should I message her? Should I drop it? Or any other ideas?
