gotta ask yourself is worth it tough
if its minor shit like wife cheatin,lost job etc just forget it
but if its like abuse or something id understand
well its simple really just track him down know what kind of person he is like can defend himself,does he have something to defend himself with.stalk his daily routine
plan to jump on him when he least expects and thats it really
just dont be surprised when the police catch you its not like you can easily beat a man and walk away from it
