We engage in annoying habits because we don’t feel what our spouse feels or we don’t care how are spouse feels when we do them.
Whether it’s intentional or not, a couple’s behavior will affect the love they have for each other.
Habits are formed by simply repeating the new behavior often enough.
Any new behavior is uncomfortable at first. Whenever a new behavior is introduced to your brain, it must form a new neural pathways before it feels natural to you. The more you repeat the new behavior, the more complete the new neural pathways become. Eventually, the pathways are completed, and you have a new habit – automatic and almost effortless.
