Quarrels are one of the essential parts of every relationship. Due to the differences in our personalities, we tend to disagree from time to time. Sporadic bickering is a completely normal thing, and it shouldn't bother you. However, there is a huge difference between disagreements and constant complaints, and sometimes it's not so easy to distinguish between these two. You should know that if you're not happy in your relationship, then something's definitely wrong and you shouldn't ignore that. A long-lasting bond is built on mutual understanding and hard work, and both partners have to participate in it equally. If you ask yourself "Why does my husband criticize me constantly?" and you have no idea why you get such a treatment, you should know that these kinds of behavior can have a long-lasting negative effect on you and your wellbeing.
