No need to get confused buddy. You're free to decide whether you want to accompany your spouse or not, that's why we are given this option to choose as per our own desire. You just have to give a reason to CIC, which is a formal practice. Because of boosting the CRS further you can list your partner as non-accompanying one, which is ofcourse a valid reason, and being the main applicant you have every right to increase your scores. Many people have done that previously and still are doing. Even IRCC has confirmed this thing by itself while answering to someone's query regarding the same concern on twitter. Hope this helps. Good luck!
Hey dear,
To be honest, the current trend has diminished all the chances of 452 in September. However, in Q4 I'm quute confident that we will witness some positive movements i.e. both increased ITAs and dropped CRS. You never know when CIC will buzz around with a new twist and surprise us. Patience is the key here! Good luck to you as well.
