Hello jam, if i were in your situation i would be very angry at him
It just not so right playing with you feelings like that, if he really loves you he would be sensitive of your feelings that you will be very worried not hearing from him for weeks!

I watched a very nice film last night its called "He's just not that into you". Seems your bf now lost interest or thinking about things or maybe he found someone else and he's breaking it to you gently Whatever his reasons, it is only you jam who can make the decision. If i were you i would ignore him and not contact him for weeks just like what he did to you, and see what happens. If you are important to him, he will do everything to patch up things beetwen you and he wil ring you a zillion times until you talk to him and he will say sorry for what he did. but if he will ingnore you again and not chase you, then its time to move on my friend and start to forget this man
