As-Salamu Alaikum - Trusting Allah but feeling the pain of repeated marriage rejections

As-Salamu Alaikum. Not sure if this is the best place to share, but since I’m among fellow Muslims here, I wanted to ask and hear your perspectives. How should I ask Allah properly for marriage? Whenever I like someone, I make duʿā for it, yet that person never seems to be meant for me. I truly believe in the ḥikmah of Allah and that His decree is just, but it still hurts when what I hope for doesn’t happen. This has been going on for years. Whenever I’m interested in someone, my intention is always to make it halal. I state my intentions honestly and try to proceed respectfully, but I get turned down for reasons that don’t always seem like they need fixing. I try to move on, but the feeling sticks. As time goes by I worry about getting older and the possibility of staying alone. I know what Allah decrees is best, but sometimes I wonder: am I asking Him the right way? Is there more I should be doing when I make duʿā for marriage? Recently I asked a man about marriage and he declined because some of my family work with him, so he thought it’d be inappropriate. I accept that Allah knows best, but repeated refusals leave me searching for meaning or at least some closure. I’m not questioning Allah’s wisdom - I’m just sharing how tired my heart feels from the waiting. I trust my Rabb, yet I needed to let this out. Any sincere advice would be appreciated. Also, please-no inappropriate DMs.
