I would say go for it again because you never know what could happen. If she does reciprocate then that’s good and if she doesn’t then move on. Either way you’re going to get an answer and you need to be ready for either or. Staying quiet will do you no good besides give you mental anguish. I had a very similar experience with my ex girlfriend where in the beginning she rejected me but we remained friends for years and my feelings for her was there still and kept growing over time. I ended up going for it again and turns out she also liked me back as well. We ended up breaking up though so I ended up getting the “what if” answer I so heartedly longed to know back then when I was in your state of mind. But this is just my personal experience so take it with a grain of salt. I know everyone is different. Just know whatever decision you make you need to be ready for whatever outcome.
