"Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice."
No one likes having to walk on eggshells around someone who gets upset or offended at every little thing they say or do. Knowing that you just cannot seem to do anything right in the eyes of someone else is not a good feeling, especially when that someone else is your spouse. A good marriage, where both partners are caring and understanding of one another, should never have this kind of pressure.
Your spouse should not be afraid to try to make you laugh or to be a silly with you from time to time. They should not have to be watching what they do or say every minute of the day. Relationships need room to breathe. The happiest married couples are those who aren't constantly picking apart the possible hidden meaning behind what the other person has said, or seeing every comment some kind of personal attack.
Keep in mind that this doesn't mean that you should let your spouse get away with being mean or intentionally offensive. You have every right to demand that they treat you with respect and accept any boundaries you may have. Not being "too sensitive" should not apply in situations in which your partner shows no caring or compassion for you.
However, if you truly have a loving and caring relationship, then you can only benefit from giving some leeway to your spouse. Maybe they forgot that you had important plans or an important appointment. Things like this happen. If they are truly sorry, then you may want to consider not holding it against them, at least not for too long. Everyone can be forgetful, no matter how much they care.
If your attitude towards your spouse is one in which you are always looking out for what they do wrong rather than paying attention to what they do right, then things are going to get very stressful very quickly. We all have the propensity to make minor mistakes and to say the wrong thing at the wrong time. But, if no one in a relationship is willing to let minor things slide, then you will find yourselves constantly at each other's throats.
In Ephesians 4:31 the Bible teaches us to "get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice." These inspirational words of encouragement should apply to all your relationships, but most of all to your relationship with your husband or wife. A good marriage has no room for malice of any sort, and allowing bitterness, rage, and anger to seep into your marital relationship can only lead to disaster.
It is better for your spiritual, emotional, and even physical health and well-being to learn to laugh, learn to forgive, and to realize that your spouse, even though they should always strive to be caring and mindful of your feelings, is not always going to be perfect. Give them some leeway and understanding, and you will likely receive the same from them in return.
