Love is something we all aspire to find, but true love isn't the only thing a relationship needs. Once one partner starts assuming that the other one will always be with them and put up with their crap no matter how they behave, that relationship is on the road to ruin. Sure, it may stagger along for many years after that point of no return, but it's a zombie love that isn't really fulfilling for either partner. However, even loving couples can find it easy to fall into such a pattern, and it's certainly possible to come out of it when it occurs - if the will is there and the baseline of respect is maintained.
A truly loving relationship is one between equals, who know how lucky they are to have their boo in their life and make an effort to show it. They might have times of illness or employment trouble where they need to lean harder on their partner, but they don't just take for granted that they have the right to such things. Instead, they say, "Thank you" and do whatever is in their power to prove that they really do intend to always put the "significant" in "significant other." So tell us about how your boo is with you, and we'll see whether they're taking advantage, or whether you've really struck relationship gold!
