Backstory: So there is this girl which I liked for a pretty long time, got introduced to her by a friend of mine but she had a boyfriend then. Got her on facebook and added her phone number when I was in a group chat with her some time ago. They broke up some time ago.

So here is my deal, I never really get to see her in real life so I need to open through facebook or text. I just don't know how, my text game has never been good. I dont really have problems irl with women. How would you guys start talking to her? Don't want to ruin this one so I probably need some advice.
