So confused about things right now about someone from my past?

About 8 months ago I met someone whom I really fell in love eith. We talked a lot, flirted and everything until there came a time when we argued over the fact that she kept throwing her ex in my face after telling me she was someone shed never get back together with. After I told her I loved her she blocked me and I havent heard from her since. I moved on cause I knew I had too. I didn't try to contact her or anything. Lately though things started popping up in my fb feed and memories about her. I come to find that she no longer is in contact with her ex. She jasnt tried to contact me but a few people she works with have. Ive had tarot readings done that say that someone from my past is coming back and all signs point back to almost this. So my question is what do I think what do I do?
