It sounds like you are torn between letting your husband surprise you with the ring and wanting to be involved in the decision-making process. Ultimately, the decision is up to you and what will make you happiest in the long run.
If you trust your husband's taste and feel confident that he knows what you like, then letting him surprise you with the ring may be a wonderful experience. It could be a romantic and exciting moment, and it would show that he has been paying attention to your preferences and desires.
On the other hand, if you have any doubts or reservations about the type of ring he might choose, or if you feel strongly about being involved in the decision-making process, then it's important to communicate this to your husband. You can express your desire to be a part of the process while still allowing him to surprise you with the timing or presentation of the ring.
Ultimately, it's important to remember that the ring is a symbol of your love and commitment to each other. Whether you choose the ring together or your husband surprises you, what matters most is the
love and connection that the ring represents.
