It sounds like she responded well to your reaction and it's good that you were honest with her. I think it takes a little time to 'get back' and trust again but it sounds like you're on your way.i also think it's helpful to look at past relationship patterns and see if there are any similarities and differences. Ruptures can be helpful because the therapist's response to them and the relationship surviving them, will hopefully help to change internal patterns and help to heal old wounds.
