I used to have a huge crush on this guy ..after 1 year I gained courage to talk to him?

I started talking to him through a social networking site as a stranger..he initially started talking to me as a stranger then we exchanged photos and later phone number..it went on for a month..innumerable sms and calls from his phone always kept me busy and dreaming..He was my dream guy and I just couldnt beleive that I was talking to him and this guy is dying to meet me..finally we've decided to meet after too much of hesitation from my side and requests from his side..I've decided to go meet him (he lives in another city-overnight journey)..until I met him things were flying up high..then we met went out to do some household shopping for him(he lives alone)..He bought the fridge that I've selected and then we went out for lunch and then went out for shopping..he gifted me a nice skirt ..and in the night we went out for dinner and he said he is interested in me and asked me if I want to be in a relation with him..I said yes..and things went on ok..things got a lil heated up..next day he is a completely changed man--he talks like no strings attached and says that he is a casanova and doesnt beleive in love marriage and will get married to whoever his mom finds...then he was very keen about bidding me farewell..he didnt even care to drop me till the station saying that he has to go to another city on business purpose...after that he stopped answering my calls and sms..but I'm emotionally so broken..I cant take this..I just feel like he used me and left me..his memories are still alive in my heart and I still miss him...I wanna take revenge on him but again I feel like letting it go..but I cant..Sorry for the long history..plz help! it's close to 3 weeks that this happened..
