Non judgmental please

So I've hurt a friend really bad this year and I did apologize once but she told me she no longer wanted to talk to me then blocked me from messaging her, I saw her yesterday for the first time since we last hung out we both smiled at eachother and I thought it was a good time to apologize but I all I could think about was the rejection she would give me and I do want to forgive in person soon idk if I should do it now or wait till the next time we see eachother which will be at the end of January.
