Breaking an engagement

I'm 28 years old man and live in navi mumbai. I had my engagement last month on 2 Nov 2014. It was a huge engagement and population was around 1000 people. Even MLA had attended the engagement. After engagement girl seduced me and we did cuddling, kissing and touched each other's private parts various times but never had sexual intercourse. Now I want to break my engagement due to some family reasons. We didn't demand for a dowry. I had gifted girl with expensive watch, sunglasses and some jewelry. In return she never gifted me anything. We also gave her golden bangles in engagement along with ring. Now they have done most of the wedding preparations like printing wedding cards, arrangement of wedding place, have paid for wedding time food arrangements. The marriage date is fixed as 22nd Feb 2014. I have informed them about denial of a marriage on 27th Dec 2014. They want to discuss the things and want to force me to get married. I don't demand anything in back but I want this to be broken without any legal implication. I want to know whether they can take any legal action or not? How can this matter be solved internally?
