I'm going to echo AutumnalTone's post. Talk to her, but don't pressure her. Keep your spouse in the loop. Getting out of a serious relationship and directly into another can be an emotional storm. It's just not possible to switch feelings on and off. There's a process involved and it can take days, weeks, months, or even years - but I don't know you or her enough to know anything about she handles her emotions or how you handle yours. Best I can suggest is that you try to exercise patience and understanding, and let her come back around in her own time, if indeed that's what she wants to do.
