On January 2012 my boy only proposed me, that time am not in a mood to love but finally I fell in love with him, then we met. After that one day he told tat his family can’t accept this relation and all so he stopped this relation.

After one week he called me we restarted our relation but felt his character is totally changed. Not calling me regularly... and we both are moving to some another country.am going to Dubai and he is going to Malaysia.

But still he is telling that he can’t forget me and this relation and all. If we went abroad we can’t contact each other for 2/3 months... but my question is he will forget me or not after 2 months?

I doubt it, if he is serious and true, but you won't know until you get back in contact with him.
