Need advice

A month ago I matched with this man on Hinge and we started talking. Initially he as very polite, kind and understanding. We connected in insta as well. Over the days we started talking more texts now became hours long phone calls. He said he was not looking for a "Situationship, 1 night stand or Friends with benefits". "I wanna be your man" he said. I thought we were seriously going somewhere. So he had to fly to India(from US) to attend a family function just after a week we started talking. We didn't meet in person until then. While he was in india he kept me updated, regularly called, kept texting and sharing pictures. I started feeling the connection too. After 3 weeks he came back and we decided to meet the very next day. I went to his place to meet him(on thanksgiving day). He cooked amazing lunch for me. We talked for hours and had a good time. Before leaving we hugged and I didnt feel butterflies I rather felt safe and calm. That very moment I got attached to him. The next couple of days everything was normal. Then I asked him a question "What are we?" he said we are in the "Talking Stage". I agreed and asked " Do you think we could be a thing?" (since he has days before said he wanted to be mine). He said that he wanted to talk to me and get to know me better but he has commitment issued. I asked him to elaborate. He said he might have to go back to India in a few months and he know that in that case "us" won't happen. I asked him why did he not mention this to me before to which he replied that he himself got to know about it today that his project was gonna end and his company would be sending him back to india after the project. I asked if there was any other reason other than that and he said no and added that his past relationship has left him with a lot of mental scars and he was not ready to go through that same pain once again. I clearly said I was not looking for a situationship and we should not take this further. He then said you are right we should just be friends.While this conversation was going on we both were crying coz both wanted to stay. I agreed to just be friends though. We had already planned to meet that day in the evening and so we did. We went out talked, had dinner, went for desert as well. Later on our way back(he as dropping me home) I asked him if we can talk for a bit. So he parked the car and there was this awkward silence. He asked what I wanted to talk about and I looked into his eyes and said: "I don't wanna be just friends". I wanted him to be my man. He said we will both get hurt if we do that coz we know how it ends. I still tried convincing him. We were both putting forward out points when he held my hands. And now suddenly I just wanted him to stay. I kept saying we'll figure it out, i won't have expectations, we won't talk about future and things like that. He agreed and we hugged again. This time we just didn't stop there we kissed, not once but multiple times. But that night i couldn't sleep thinking that I can't do this knowing this is all just casual. Next day we texted and chatted on a call like everything was just normal, but it was like a fuv=cking time bomb inside me. I texted him in the evening that I was coming over and he agreed. We met, we hugged and kissed again. I asked him how is it so easy for him. He said he knows how it was gonna end and he didn't want either of us to get hurt at the end. I asked him why is he not even trying to make it work, maybe his visa gets extended maybe things fall in place and "us" really happens. He said he know there was no possibility of his visa extension and that even if he tries it wont work out. I got devastated. I went back home and cried my heart out. Next morning I texted lets just not walk on this path and he said that what he said the very day we had this discussion. We then agreed on staying friends. But I can't get over this attachment. What should I do ??
