3rd Secret. Relationship Battles.

           When two people move in together, couples tend to discover pretty much the same thing no matter who they are – that they are two different people and living together is harder than anyone ever told them. Love conquers a lot of things, but it is no match for living day-in and day-out with another human being (especially if you’ve spent years on your own).
           Prepare yourself for this challenge by choosing what arguments you want to turn into a full blown battle. For instance, do you really want to start a fight over the toothpaste cap or how clean the shower is? Or would you rather reserve your energy for the discussions over finances, kids, and career paths (you know, the things that might really matter to a person). Too many couples fight and bicker over the dumbest things, especially when put into context of issues of true importance.

2nd Secret of LTR. Communicate.

           Relationships live and die not by the sword, but by the amount of discussion. If two people can’t find a way to openly and honestly communicate their needs and feelings to one another, the relationship doesn't stand much of a chance long-term. Couples must find a way to communicate regularly, openly, and directly.
           This doesn’t mean waiting for an argument to tell your significant other how much he bothers you with his throwing his clothes on the floor instead of the hamper. It means telling him when you feel the need to, and to do so in a manner that is respectful but assertive.
