In your horoscope we see that Jupiter is conjoined with Rahu which is not good. Saturn in lagan aspects the 7th house. Marriage should be done after proper matching of the horoscopes, to avoid marital problems in life.
Mercury (lord of 7th) is in a friendly sign. Jupiter is in his own sign.
Given that Saturn is in the first house (neutral sign, so good), you might be a little bit strict and orderly in life. Depending on the situation (profession for example), some amount of order is good.
From an Astrological perspective, I don’t see any obvious evidence of a marital problem.
To my mind, you will not have any problem with marriage since your have a potent seventh house and the fifth house indicating marital happiness and happiness from children. I think your doubts are ill founded. Read my blog to understand my evaluations.
