Should I leave this toxic relationship?

You do it like a good leg wax, just take a deep breath then rip it off! There's no easy way to do these sort of things, as the old Nike ads used to say, "just do it"!

There are many who have been where you are now. Just put on foot in front of the other, and walk, honey... or better yet, run, run fast, and far away from your future psycho ex-boyfriend!
