To be honest it's her family, and she has the right to say no/yes, on the other hand thinking from your aspect, the reasoning seems off...what does she mean that it's not a right time? If they already know or have an inkling then things are going to be fine. Does her dad know? Or that he is just guessing and she has not told him? curious if you say most of them know, does that mean her immediate family, her siblings if any, her parents know!

Her mom knows and she told her dad last year, before he meet me at her last family event! She said that she don't won't me to go because he might tell her I can't stay at the hotel with the family but she can and she don't won't us to spend money on a hotel so she has to stay with them at the hotel they choose to stay at! I respect her and her family! She's scared to stuck up to her parents about us! There was a time where we was at her mom place(her parents are divorced by the way) and her mom found out about our engaged and he dad made me get out Her MOMS house and talk crap about my parents for accepting my sexuality and she didn't say nothing we just left!

I take her to my family events all the time also and she avoids talking about US going to her family event!

As you've taken a huge step forward becoming engaged, it makes sense to be acknowledged as such. Then, there's this reservation from her. She seems to like the fun and attention of commitment, but isn't sure how to display or announce it properly. I'm guessing here that she wants to know how to say it in a more comfortable format. She is still hanging on to a certain role that is comfortable and doesn't know how to step out of that role. Am I guessing correctly so far??

Yea your guess is right
