The issue of marriage proposal is a very tricky one. You can never control it because you are two different people with different views and wants. Someone asked me a similar question a year ago and I told her that just like life, there's no formula for this things.
You given her a guide, to just live her normal life and try to release some of the pressures. I know what it means for a 27 year old girl in this age, especially when your parents and families are involved. I hope it works out well for Rachel.
