There are so many sensitivities and emotions floating around. Your ex-wife is learning some hard lessons and now she's the fragile, vulnerable one whereas when she left you it was you who was fragile. No one likes to be the fragile one, but you and your ex-wife are both fragile as you try to navigate a potential reconciliation. Maybe you two can agree that you'll both make mistakes and you're both learning and you'd both love for this to work out but it's a process with an uncertain outcome. We all have times when we have trouble controlling our emotions. What I'd be looking for right now is whether she's sorry for her outburst. Did she recognize her fault and correct herself? Is she trying to learn and improve herself? It sounds like your reaction was fine. I will try to get more caught up on your situation as soon as possible.
