Desperate after breakup. Should I try?

Will try to make it short. We were dating for nearly 8 months, had distant relationship. First 6 months were great (out of it we spent 3 months together without distance). But after he moved from his native city to new country for postgraduate program. In the beginning all was fine but suddenly he started to change. Nevertheless, we were every single day in touch. We were talking about how we miss & love each other. I tried to support him and understand: new environment, new people, new Life but he was more distant than before. In general he was saying that all is fine with us but I was anxious about his changes. Once I told him about all that, he said that all is fine but suddenly in two days called and said that he is not sure and want to make pause to understand what is going on with himself, he is lost. We discussed it. I said that most probably it’s due to all changes and we should not make fast decisions. Next day he called me by himself and said that fully agree and we should give it a try if I’m still in. I agreed.
In two weeks I went to visit him, first week was great, for a weekend he invited me to join him to go to another country for some business stuff. It was very exhausting due to much travelling and last two days we both were very tensed due to tiredness. In the eve before leaving we had dinner and I asked if all is good, he said yes, just tired. We agreed that I’ll go with him to airport. Next morning I woke up anxious cuz of bad sleeping and dreams. Told him about it. He was also tenced. We went to airport. He was weird. I decided to leave him in his thoughts. He came back to his city. For three days we were talking as usual, had calls, all seem fine. Suddenly next day he called me and said that we should split up, he needs his space now even he feels that he would regret but he doesn’t want keep me waiting. I asked about other woman: he said no, just so far he doesn’t see our distant relationship (in the beginning he was initiator to date despite the distance and give it try even we were apart). During that last talk I made huge mistake starting to ask him to stay, used stupid arguments to give us a chance. Now feel very bad about it, can’t forget myself for begging. Seems it’s the end.
