When it’s the right person for you. Trust me you will know it or as you say it will click and you will know when it’s the proper time to propose and move forward in life…..
The question you need to ask yourself is. Are YOU doing your Hishtadlus? No not just your physical hishtadlus but your SPIRITUAL hishtadlus? I.e. are you davening to Hashem daily special tefillos asking Hashem to please send you your chosen zivug? And as quickly as possible? Are you having the proper bitachon and emunah in Hashem? (Faith and trust in Hashem) and not turning to others for help but davening directly to Hashem the king of kings to help you get married very soon.
perhaps this tip might help you if you answered no to the last question. Hashem has already chosen who your lucky wife will be over 20 years ago 40 days before a person is born and has her/him waiting for you to get engaged to each other. Hashem now is just waiting for your Hishtadlus to call out directly to Hashem for help and put your complete faith and trust in Hashem.
May Hashem answer all your tefillos and send you your zivvug bkarov. Make sure that you let us know in the CR when you get engaged
