I recommend that you do not sponsor him at this time. It will leave you open to a three year commitment to support him, and if things DO go bad, you are going to have potentially serious problems. Also, if you now reapply, you will be bound to live together as a married couple for the two years after his PR is started because your marriage is so recent and you have no children together.
If he applies PNP, these are no longer issues as he will be independent from you.
Seriously, do not jump into this. Wait and see if you can make a go of things before you even think about replying for sponsorship.
Most importantly, and I can't stress this enough, GET AWAY FROM BOTH YOUR PARENTS to start your own lives together.
You are heading for a nightmare while they are still involved with you both..
More questions will not change the fact that your marriage is at great risk unless you decide to fix it first.
You have now had a wide range of very good advice from lots of different people, with much life experience.
It is up to you to decide if you want to follow it.
