I am a newly married gal from India. Mine was an arranged marriage by dad. We had 3 months before our wedding.?

My parents were satisfied that they have chosen the best for me...I was very happy at that time. We talked a lot and built a solid foundation... Slowly I started luving him and believed he was the prince of my dreams coz he has such a wonderful character. But after a month of marriage, I found a letter written by him.. In that he had specified that he had luved another gal in his office and that gal had left him coz of her parents and a better guy who will provide her more. So in desperation he had attempted suicide and was saved by his parents. Now he claims that it was mere infatuation and he truly luvs me but I am not able to believe his love wen he was ready to sacrifice his own life for that stupid gal. He says that he cannot live without me.. Whenever he touches me, I torture myself wid images of him wid tat gal... But I luv him and I want my marriage to succeed.. I wanna have a true love life... Any suggestions?
