Relationship trouble?

I joined a new college . Few days into the college and there was this guy who used to help a lot with studies and all since i with one more girl had joined late. Soon we started chatting a lot on social sites for long long hours , sometimes we ended up chatting for the whole night.

He is a nice guy , then we started chatting on phone and one fine day he asked me out.Though I really liked him but at first I said no , but he convinced me and we started going out. He took me out on first date and it was really awesome , not the date but the way he behaved throughout the date. I had started falling for him .
One month into all this and I was sure that yes I really love being with guy and it is possible that I may be in love.H e said the three magical words and I replied with I Love You too.He was caring , loving , supporting and everything I had ever dreamt in a guy.I am not a very good looking girl but somehow he found me beautifull , I used to get compliments on a daily basis. May be that was the reason I was so hooked into him because I was not used to being complimented so much from a guy except for my friends who shower me with praises and compliments all the time.Neverthless the fact was I was in love with this person.Soon our conversation started getting intimate , we started hand holding , hugging tight and touching each other and yes we always ended our conversations with kisses on phone. Wake up calls and good night kisses were routine as it should be in a relationship. I was very happy with him.
One fine day we were on video chat when he said that he wanted to tell me something and the thing was that he will never be able to marry me , he has some issues with his family and he has to marry someone they choose.I instantly started crying and he was really sorry.We were at our homes at that time , vacations were going on.I thought a lot and somehow tried to accept this . Holidays ended and we came back to our college and we kissed and crossed level 1.But he still wanted to discuss that marriage thing. He made me sit one day and told me that he can not marry me because he is waiting for someone to come around and say yes to marry him. And that someone is his ex. His family knows the girl and girl’s family also knows him and that’s why now he has to marry the girl if she says yes and he is waiting for that.And once the college is over so are we. I was literally devastated but I dint react immediately , I tried to understand all this , but I could not.H e said he does not love the girl but the talks between he and her family had moved to such levels that he can say no to them now , other than that he said our religions were different and so we will face problems marrying.H e said had it been not so he would not have any problem marrying me.I immediately cleared this confusion of him , my name is of different religion but not me.Ofcourse he was not going to say anything now.

That night I stopped myself the whole night from crying but that was the only thing I did. My eyes had swelled.I dint know what to do now , whether to shout at him or try to understand his situation.All this while I had not thought of marriage , we were just 2 and a half months in a relationship and this was too less a time.But I was devastated with this whole stuff.I tried being with him like I used to but I was not able to , it was very painfull. I tried maintaining distance but he dint let me.Even after all this he tried convincing me that he really loves me and please don’t go away from him.He said that if I will cry god will never forgive him so please stop and stuff. Somehow he dint let me move out of the things.I dint know what to do so I started behaving normally but somehow our everyday conversations ended up at that girl.I was not able to concentrate on anything , I was getting depressed I don’t know why.Exam time came and I had noticed he had started maintaining distance , all those good night kisses and wake up calls had stopped.I was feeling even more horrible.But he used to spend some time with me daily , if I ever look upset he calls me and asks me what happened and tries to make me feel good. These things continue till date. He cares for me but somehow he has moved on . Bu he insists on dropping me home sometimes and helping me with other stuffs. I f he sees me alone he comes and joins me. I f he sees me in mess having breakfast/lunch/dinner he comes and sits next to me and talks and I pretend everything is fine .After the exams get over he comes running after me to ask me how did it go and advises me about how to study for the next paper and stuff.

We are friends but I don’t like this whole thing. It hurts a lot. Infact it hurts like hell , I am not able to study at all , I usually spend some 2, 3 hours crying everyday and wasting my time while he is doing brilliant.Iam happy for him but I am not able to get over him neither do I know how to handle this whole situation.Soon our exams will end and we will be siting together in classes . I am dreading that situation.Its easy pretending that you are okay if you see someone twice or thrice in a day but when you see someone in front of you all the time it is impossible to hold back your feelings.

I still love him and I know there is no chance we can be back together but I want it to happen. I miss him and miss him a lot.Tell me if its possible to get back together or else tell me what do I do to move on……Please help….
