this is why it's weird. If she had given me the silent treatment during the rship, i wouldn't think this is so strange. But she wasn't anything like that. I was the quieter one
Perhaps she is not responding to you because she is very done with the relationship, and is trying to detach, as you should be doing, too.
Understanding our ex's behavior is one thing - obsessing over it is not healthy.
There comes a time when letting go of something that has caused us harm, including someone we felt close with (even though in many ways we're 'comfortable' with it, being used to it), just has to happen or we decay more than grow. We can turn what they did to us against our own selves, perpetuating those pains and making them worse.
Very wise words! Time to let go, Diana, and start focusing on creating a new life without her.
