I would like to propose to my gf, but I don't know if she's ready for that. I don't want to get turned down. How can I find out if she's ready too? I know she loves me but I just don't know if she's ready for the next step.
It sounds like the two of you have some more discussing to do. It should be a mutual decision to move forward. You will know when the time is right, but you are correct in waiting. If it is meant to be, it will happen.
