Questioning my brothers girlfriends parenting- did I cross the line?

I need some peoples opinions if they feel like I crossed any kind of line, I’m feeling like I may have and I feel kind of weird

My brother is dating a girl with 2 kids. They are 5 and 4 years old. My brother has been with her a little over a year, and they are getting pretty serious. We spend a decent amount of time together, not as much as we normally would have because of covid, but during the summer we did outdoor play dates a couple times and we see eachother on holidays. My kids are 1 and 2 years old.

So her kids are like unicorn kids. They are so well mannered and so well behaved. Their manners are better than most adults I know. They are so sweet, and really really good kids. I’ve never met kids like hers. However she is parenting them, I want to do the same because she’s doing a wonderful job

So my son recently turned 2, and he’s really testing boundaries and not listening. He’s kind of a monster and i honestly don’t know how to handle him and I find myself giving in to his tantrums which I know is only going to make him worse. I don’t know what I’m doing to be honest. I was texting my brothers girlfriend, giving her the situations I was dealing with, and asking how she would have dealt with them. I was asking her a million questions, like does she do time outs, how does she discipline them if they ask out, how many warnings does she give, what does she do if they refuse to eat, like so may parents questions, things along those lines.

Then I was thinking like I hope she doesn’t think I’m prying too much. I’m not overly close to her, but I don’t really have any other parent friends. Do you think she’s insulted I asked? I know parenting can be very personal so i hope I didn’t over step
