This would be communicating, not confrontation. Think about the reasons you're GALing. You weren't happy, there are parts of your life that you don't like. That's what you tell her…the DB strategies aren't tricks to confuse her into returning; they're tactics to make you happy, attractive and better at managing your relationships.
If she confronts you about your behaviour, try to turn it into a discussion about the specific actions, not strategy. But most of all, listen. And try to understand the purpose behind the questions, not the questions themselves. For example if she says "why are you always going out all of a sudden?", answer with something like "what is it about my going out with friends that has you concerned?" That way you dig further into the reasons for her questions and you can answer the actual question behind the question.
Resentment occurs when we aren't doing what we need to care for ourselves, though we expect others to do it for us.
