Girl is ignoring me what should I do?

It does sound like you have good chemistry together, but don't forget if she has just come out of a long term relationship, she might not want one straight away. So she might have been a bit scared? I think you should play the elusive card too, she will come around when she's ready. She might just need time. But let her come to you, I doubt she'll walk away, she is just enjoying her freedom right now. But it will get boring soon enough! Good luck :) x
