Ask Dan & Jennifer

I'm dating and living for 2 years with my botfriend .We loved each other since first sight and we made a lot of plans for living together all our life.One year ago he moved in to my place because he wanted to be near me.In past few months I have problems with him,because he is a kind of person that becomes irritated fast.He is a professional footballplayer and at the moment he has problems about his team(he broke his leg recently and the team is going to end its existance,because of director),also he has no parents who would help him in everything.I feel like all this problems fall down on my head.He screams at me,he do not listen to what i say,he do not want to help me about the house,I irritate him once in a while and i found myself crying all the time.
But there are and good times also.I get a lot of gifts from him,we go to different nice places,i know that he wont ever cheat on me...On the other hand is another problem that bothers me.We are living in Europe,and my parents want to move to Canada.I was so excited abot this,coz this was my dream to live in Canada,and I want to go with them there.But my boyfriend do not want to leave Europe ,he wants to play football in Italy,Germany or somewhere else...He says that if i want to go there i can go,but i have to wait for him for some years...Honestly I don't know what to do...he wants me to be near him and support him,but i see the ugly way he acts with me everyday and how i forgive him everytime...he changed a lot since i first saw him...also i want so much to live in Canada...I think such a girl like me could find someone better for life,but I am afraid about what will be with him and me after this?! Will I love someone like this or this is just my first love? I don't know if it worths to break up with him?!

Please help me...
