Anitha,
Don't feel scared. It is all what you believe. Why are you letting this horoscope stuff dictate such a big life decision? Horoscopes are a crap shoot. Sometimes the predictions are true, sometimes they are not.
In life, some marriages fail and some work, but I feel it has nothing to do with horoscope and everything to do with the couple's attitude. You will make or break your marriage, not the stars billions of miles away. If the pundits really had all the answers to life, there would be zero divorce, no death from earthquakes or tsunami, no poverty... because they would have all the answers to make the world a perfect place.
Let me tell you a quick story which I have told many times before to those asking about horoscopes. My dh had an ARRANGED marriage before he married me. The pundits said it was a PERFECT MATCH, match made in heaven, blah blah blah. In less than 2 years, my dh and his ex were divorced. So much for the accuracy of horoscopes, right?
Then me and my dh had a LOVE marriage. My inlaws had horoscopes done and what a surprise, I got the same answer you did. We were doomed, bad things would happen, it was a horrible match. We didn't care. We went ahead and got married anyways. This coming January it will be 3 years we've been married. Add in the time we spent dating, and we've been together about half a decade! Last time I checked, we are both still alive and happy.
Have faith in God, faith in this man you love, and faith in YOURSELF. That is what's most important. Good luck.
