And here is the BUT. It is very likely that she will now retreat ... she will do this because it is a human reaction - it will not be about you, but about her, questioning what happened last night and what she thinks about it and what it tells her about herself.
How long and how far her retreat is will be somewhat in your control. If you let her retreat and stay where you are, lovingly detated and a true friend with no expectations, you can expect her approach again, but chase her, show her you are pursing and she'll go much much future away.
Please Frank, play it really cool now, it's quite a critical time.
Take care, I'm thinking of you, V
