Hi Yu,
The incident itself is concerning, but his response to it is even more so.
“I told him I was not comfortable with them being our godparents. And he told me to get over it because he won’t change it, he is the one taking decisions and he won’t let them out”. This is a major life decision that requires your input. It is not right for him to make this decision on his own.
“He told me he wouldn’t discuss anything and I was wasting his time.” It is important to discuss any and all problems that occur in the relationship so that resentment and anger don’t build and so that his and your needs are met. You need to be able to voice your concerns and have them heard.
These are definitely red flags and should not be ignored. I would definitely take time to think before taking the relationship further.
Take care,
M
