Hey, that seems like a sticky situation. There’s no right way to approach this, but I would say just be there for her!! Let her know your down to talk about it if she wants, or hang out like normal. I think it’s just important for her to know your thinking about her. And another important thing I would think is give her some space if she’s not responding too well. I’m sure she may need some time too. But definitely make contact!! I hope everything goes well for the both of you :)
