Relationship

Sometimes I feel so upset about my decision.  After deciding rather or not I should tell him that I love him, the logic side of me tells me this relationship might not work out.  How am I supposed to stay with him?  I will need to give up so many things .... am I ready for that scarifice?  I love him...even when our communication is very poor.  My mind tells me that we can be together... but what if he really has to go back to his country?  If I can, I want to go with him.  He might not agree, but I can't do anything else.  I will try my best...but is he ready for it?  Sometimes...I think he isn't as serious relationships as me.
