I'm a female born on 3.26.57 and beginning to wonder if I'll ever settle down with my soul mate!

I kept dating with the hope one of them could be the very one, I'm tired of disappointment after disappointment and I'm not getting any younger.but now I'm dating a man born in 1965...all I know is that he's a Gemini dont know the day of birth.
COULD he be my soulmate or there'll be someone else?
Thank you
