It takes two
One person can work hard at making a relationship work, but he/she would be working in vain if the other don't participate or contribute to the relationship. Then, when the one who has been trying his/her best to make it work walks out, the other person has the audacity to swear they did nothing that warrants the end of a relationship. If you're one of the ones who don't talk to your mate, support, or try your hardest to make it work, then step back and allow him/her to be with someone who will.
