Her best friend is one of my exes who I dated for about 2 months a year and a half ago. We broke up and there were some bitter feelings but we have gotten past those and made up now. She also has a boyfriend of over a year and seems to be happy with him. We want to tell her that we are happy together and that she should be happy for us but it would be "breaking girl code" and she doesn't want to lose a best friend over a guy. 

It could either go really good and that she is happy for us that we are extremely happy together and the rest is just water under the bridge, or she can freak out about it and ruin what we have. 

As well we haven't been seriously dating for a long time but we have been close friends before that, so it is not like this has been going on for 6 months behind her back. We have also not posted anything on social media about us nor does anybody know about us yet.
