Would you talk to your ex after 5 months of no contact?

me and my ex broke up nearly 10 month ago the last time I had contact with her was 5 month ago, I end the relationship and being perfectly honest I was a d*** about it, however she got me back and things didn't end on a good note.

I sorted my life out and now I'm completely different, I've got over what happen between us and have no bad feelings towards her or her current boyfriend. Saturday gone I got a text from my best friend (who is a mutual friend) asking if I liked my ex still, he told me that at the party they where having that she said she missed me and someone asked her if she would get back with me she said nothing so they took that as a yes then she said yea after that she got my friend to text me and then to ring me but my phone was dead but she is still with her other ex/current boyfriend but clearly isn't happy.

I was thinking of starting to talk to her again simply as nothing more than simple conversation however I've been the happiest I've been since I stopped contact with her and I'm wondering whether contact would be a mistake or harmless.

After 3-4 month from the break up I tried to get back with her, this is when she got me back, leading me on and messing me around, sleeping with her other ex and ignoring all my texts/calls,

I sent her a fb message saying sorry and how I cared about her still and had accepted things and was moving on but hoped we could be friends, she show it to her other ex and they took the p*ss out of me and 2 friends and my dad over a fb status.
