Does any past life karma cause my multiple failed relationships

I am Aditi Sharma from Bihar. My date of birth is 19th March 1987 and time of birth is 8:59 PM. I’ve had multiple failed relationships, and every time I feel like I’m getting close to marriage, something unexpected happens to break it. Could this be due to past life karma? Does my horoscope show any karmic debts that might be delaying my marriage?
