Relationships aren't worth it, they waste time, money, energy, and emotions. If you've been fed up with giving your all to someone who won't give their all to you, or you're stuck in an abusive (physically, verbally, emotional, etc) relationship, or you've been accused of cheating or cheated on, of if someone broke up with and wants you back and you know you're better without them, or you're stuck in a relationship with an depressed or suicidal person, you understand the pain, the struggles, the nagging feeling in the back of your head telling you to apologize even if it's not your fault. Your friends can defend your lover, and you listen to them. But even then that feeling burns through every human moral you've felt, and it dehumanizes and will burn you leave you desperate and helpless to the other person. Because you can be too selfless, and sometimes you deserve to be selfish, and do what's right for you. That's why love hurts, and love sucks.
