Until he does what he said he will.. i don't want to see his face or even talk in anyway?

he might read ques n answers.. but i dont care... last time i patched up wit my bf oly because he told me he'll do one thing for me.. but now he's saying he can't.. wel.. he HAS to do it now or after years.. IF he wants me back.. he cant slip away everytime and this time its for sure.. i know wat he'll do now.. he'll say he's leavin to another country n come to meet me.. but i don wanna meet even if he's dying.. i dont want a cheat in my life.. well.. he'll suffer the **** out in his life for wat he's put me through.. GOD knows it.. no matter where he goes or when he comes back.. i'll see him only after he does it.. but if he drops into my house when mom dad r der.. how do i shoo him off ?
