Looking at the horoscope matching we see that the Rashi of you both is Cancer and Aquarius, which forms the 6-8 bhakoot dosha, which is not good. The 6-8 bhakoot dosha indicates health problems after marriage to the couple and problems in the relationship. The Grahmaitri score also in your matching is weak with 0.5 out of 5. Despite Guna milan score being 20.5 the overall matching is weak due to Bhakoot dosha. You should check the Grah milan to make sure the planets are well placed and offer marital happiness after marriage.
