Family Issues?

[Kitkat]

ok so my step dad and my mom were fighting last night, and ya people arque, but last night wasn't a normal arguement. my mom was crying, well sounded like it. and she was yelling " what's this! ( threw something at him)" then she was saying something about him lying to her for the last time, and that he promised he wouldnt do this again.... and it was something bad i guess, but she wont tell me and i think i have an idea of what its about. but last night she told my sister and i that we are going to pack some cloths up and tommorrow were going to leave when he is at work. we never left but she keeps saying she doesnt know what to do.

do you think this is the end of their relation ship? will i not be able to see my step dad again? this sucks...
