Probably the weirdest ex story ever?

So me and my ex were together for 3 years. I broke up with him 8 months ago. He's been with 3 girls since then. When he broke up with the first two, each time in between he would try to get me back. His most recent girlfriend used to be my best friend and she just cheated on him a few weeks ago but they're still together. I was starting to get over him but weirdly enough, I had a dream about him asking me to hangout while he still had a girlfriend this morning.. I got just home from work and saw on my phone he had requested to be my friend on Facebook today.. wtf is you're explanation for this... really freaky.. what do I do? Accept or ignore..
