Do watch the video I listed for you. What your wife said to you is very typical toxic behavior where the abuser blames the victim and refuses to take any responsibility. It’s not your job to make the children spend time with her. Do NOT let your wife lead you to accept any blame.

Also, try not to engage your wife at all. Each conversation will just be toxic and her own effort to get control and power. Also it’s best not to give her any information. She will only look for ways to twist and gain leverage just the way she did with you that you described in your last post. It’s important you learn not to give your wife any power. You have been slowly gaining in that skill, it takes time.
