i must be ancient....but here is what i think. what you did (make a boy friend) is not right in islam so please do not say Alhamdulillah ...when something that is haram goes well for you.
secondly , this guy is avoiding you ...well there is'nt any commitment like nikah between you right? so why do u expect him to NOT make another girl friend. he did it with you.!!!!
if you two fell in love the right thing to do was marriage right away and not continue seeing each other.
