For my scenario, my bf has some commitments that keeps him busy but yet we want to hold our wedding nxt year, so which means we have to start planning now.
And then, he did mention that he'll definitely propose, but he wants to do it properly and not just for the sake of it, so that's why we came to a conclusion that since he's so busy now, we do the bigger items first, like setting dates and venues etc.
Once this commitment ends in July, he has more time to plan the proposal for me, and I am comfortable with this arrangement.
So eventually, it boils down to how comfortable you are with the arrangements.
So Strawberry, if you really want the proposal before anything else, maybe you can drop some hints or tell him honestly lo. =)
