My partner gets annoyed if he says no to something, but I still try to convince him otherwise, by making cute puppy eyes, doing sad faces. He finds it emotionally manipulating and thinks I should respect his boundary, if he says no then i shouldnt try to push for something. Am I the problem?

I recently moved into his apartment while we are on the hunt for a bigger place for the 2 of us. We agreed on having a 2nd cat. I found the perfect cat today, ready to be adopted but timing wise it's early by a few weeks. My partner gets annoyed because I tried to convince him to adopt it now rather than losing this opportunity

Other small things like "can I use your vape"cause mine is in the other room or finished.
