Two people close to me got married with a similar path leading up to the marriage. In both cases, one person proposed, the other one wasn't ready. They both waited until the one who wasn't ready felt ready.

The outcomes have been different.

One ended up divorced partially for the reasons that kept them from getting married early on to begin with. It just festered for several years and exploded after the arrival of the third kid.

The other one is still going strong, and the fact they waited before getting married has made their relationship stronger and based on a deeper understanding of each others expectations. Taking this extra time has been a net positive for them.

Up to you and her to figure out which of these two outcomes is most likely for your specific case. Or any other potential outcome I have not proposed here, this is likely not the only two outcomes possible~~
