Dear Yogi,
Please read my article https://astrologymag.com/marriage-failures-how-astrology-can-help on this site and you will get to know about Manglik and its effects. It is only just like you are dark or fair in colour or tall or short in structure etc. which will not make any impact on your life.
According to the definitions of astrology, you are not a Manglik due to the conjunction of Jupiter with Mars nullifying the effect of Mars in the 7th house.
However your 7th house is very weak with only 30.54% strength and unless you choose a girl with a well compatible horoscope, you could have problems with marital life.
Best of Luck.
