Damn kid, I have bad news: Bad taste is hard to fix.
However! If you cut your losses quickly and move on, you'll find the right person eventually. Because blind squirrels! Nuts! Etc!
To avoid wasting time, just review the handy checklist below, written by the always astounding Frida Kahlo. If your current situation doesn't pass muster, you might consider bailing.
Of course, there's a good likelihood that your next situation will suck too (due to your horrible taste in men/women, remember?). If so, bail again.
Eventually, you'll find the person that passes the test. Someone that brings illusion, coffee, and poetry.
At that point, stop bailing. Like for real, stop bailing.
