A long-term relationship or marriage can be many things. It can be fun, it can be sexy, it can be joyful, it can be the place to raise kids and take on life together. It can also be the place where tiny annoyances can become lingering frustrations, which can turn into full-on conflict. Whether it is petty bickering or a deep, possibly game changing fight, most people don't really look forward to those tense moments when it can feel all too easy for things to get hurtful.
