I really need some honest advices

Hi community, I really need some advices. I've been having a Long Distance Relationship with my boyfriend since January '15. I met him on online dating site last year and decided to have a relationship after chatting for 3 months. I lived in Asia and he lives in Europe. 4 months ago I moved to one country in Europe to continue my study. Since the beginning he knw that I plan to move to Europe to study even tho we arent living in the same country but we visit each other every two months. At first everything was great. We try our best to love and understand each other. I have to confess that I can be very emotional sometimes and I easily say I want to break up. At first he always said sorry and told me not to run away. I know I made mistakes and I shouldnt easily break up with him whenever we had a fight. One day he gave me an article abt personality disorder and said that I might need a help. I thought about it many times. I try to be open to myself. I try to be honest. I told him I need time to think about it. I read some tips how to control emotions while having a fight, even include inhale exhale and count to 10. He said that I make progress. I was so happy and excited that we could renew and fix our relationship problems. But then something happened. These 2 weeks he barely text me and when I ask why he doesn't reply he always say hes busy. These past 3 days he even ignores my chats. And even if he answer me, he answer coldly and shortly. I asked him once why he's so cold, but he said don't make any drama anymore or I will leave you. I'm trying to calm myself and not confront him. I try to think positive, maybe he is tired or too much pressure on work. I haven't asked him yet to discuss or talk about it. I feel like it's only me now who fight for our relationship. I really hope I can get some advices here. What should I do? Should I end my relationship or stay? Tweet
