Nobody here knows you well enough to give you an answer. What is “going for you.” What are your issues? Is there an obvious reason why you are having a hard time? Are you looking in the right places? I would recommend finding a mentor or ask a shadchan why she thinks you are having a hard time.
Having said that, it’s possible that there aren’t any issues and Hashem is being ‘misaveh le’tefilosson shel tzadikim.’ Keep on davening! Keep on collecting zechusim!
