看不出你老板的恶意

Your manager is giving you an opportunity to move on. Without going through HR, he will not have to record your performance or will just provide an average rate. This is actually good for you and this is why you didn’t hear anything from HR.

Have you thought about why you were not a good fit?

By reading your written English, I can perceive that your manger might have had communication or quality issue with you. With respect, I may say that your writing is poor, with misspellings, grammatical errors, in consistent tenses, and broken sentences.

If I were you, I would take his advice and look for internal opportunities first. Should it not work, I would thank him for his support, take severance package, and just leave.
