True Long distance what should I do.

I had a relationship with a stranger from a different country since 1 year 9 months. We both loved each other alot and I waited for the day for him to come to my country and get married. We had to go through many hurdles like waiting for a long time for his nationality visa and many Things and when days came near for the day I waited we had many arguments frequently. HOWEVER we still continued to work on the goal of getting married. He got his visa and tickets. For a few a hours for him to fly to my country we got into an argument again the Argument ended without getting soughted at last he just said his family has looked for a girl for him he can't come to my country to get married. I assumed it was just to just a false thing he said bcz of our fight and Argument because it had happened before too. He went inactive for the whole night. I was broken and cried the whole night. Morning I tracked his flight it said checked in. I checked with my friends they said he will be arriving today night. My family also was waiting for him with all the marriage preparations. I forgot all the fight and Argument we had previously and went to Salon and then to a store got my new outfit to go the airport to recieve him. As it was his wish to see me in that kind of a outfit. Then bought flowers. I thought he would give me a surprise. His was inactive on all the social media platforms. No call no message after argument. I was just tracking his flight. That night I go with my family to the airport and wait for him for 4-5 hours at the arrival. Before that asked the officers and the staff at airport after waiting for him like for 3 hours I am told that he has not boarded the flight at all. In sense he did not leave from this country at all. I was shattered I come home and call his friend and ask for him and cry like ***.. I spoke to him and and asked why he did this with me. On that day which we waited evry second. He said his family has already got him married forcefully. They were from a different country. They have bought a girl on his name and fixed the alliance. He did not tell me clearly. My heart of broken into pieces I had no words. I slept and got up with next few days he convinced my and my family again to come down and get married. And said all that was false. Somebody had brainwashed him about my country that it is not safe and people would take away his money and etc. He did not feel safe and do he dint turn up that day.. but now he wants to come and get married at any cost. The other night my family gives him another chance to come and get married to me

He booked another ticket and after booking he starts questioning me with a typical and hurting questions like u will have to help me in expenses after marriage and then also told it can take upto one year for him zo send me visa to join in his country.. process is not easy..again with this we got into an argument. Then he says we have 0 compatibility how we can get married and stay like this in future. I started to cry

Because that was hurting. After a few minutes with the argument in the heat of moment he says there is bitter truth I should say you that I am already married since 6 months. I hid this from you because of loosing you. Am sorry. Please forgive me. But I cannot explain how much I love you. I don't want to loose you and I am against this marriage.. that girl is with my family in other country. I am forced to do this. My situation is like this. The place I come from is like that we have no way to convince them they wouldn't agree.. without my permission My family has committed this marriage and next time I go to visit them I will have to see that girl too. I AM JUST SHATTERED AND HAVE NO WORDS TO EXPLAIN THIS. HE OFFERS ME TO BECOME HIS 2ND WIFE. BUT I can't do this.. Nor It is Easy to forget this relationship. 24/7 vedio calls that attachment and addiction is killing me.. I am sure even he is facing the equal pain in his way and misses me...What do I do??

He emails me saying he is missing me Every second. And have been pain. Needs me. Also he has no interest on the person his family has got him married.
