Stay NC. It looks like a big drama is probably playing out between your GF and her ex. You need to let your GF do this in her own time. Your intervention is probably only going to worsen your own standing in your GF's eyes'. Her messages have been clear - stay away.
If she is meant to come back to you this will happen in time. Trying to maintain contact seems to always end up in an argument so don't do it. Either she truly has changed her orientation and that's it, or she hasn't and she will only be able to continue the lie for so long. In the interests of your own well being try to stay away.
Sometimes doing nothing really is the best thing - I get the feeling that by making contact you are just pushing your GF into proving her right and you wrong. She has to decide for herself and you need to work on making a life for you while she does that.
