Problems arise in every romantic relationship. It is how you solve your problems that matters the most. It is much easier to solve problems if you can avoid personalizing the situation. While it may be natural to want to assign blame and attack a partner for what they have done, it is rarely effective (see, talk about problems).
Research is continuing to reveal that the more you can depersonalize problems and take a neutral or more objective perspective on the situation, the more likely you are to work things out.
