This is really your opportunity to shine and respond in a calm, kind, and gentle way. Now, you may be thinking this really isn’t fair because they aren’t a safe place for you right now, which is right- they aren’t and often don’t have the capacity to be.
At this moment, you get to be the bigger person, you get to respond in a way that shows your true character. This doesn’t mean it will be like this forever, but for right now, you need to stay on top of your emotions and be his or her safe place.
I’m not saying this is easy. I know this hurts and I know this will take all of your strength, but this will give you the best chance of putting your relationship back together.
