Unfaithfulness
This occurs when a spouse seeks extra-marital affairs outside of the wedlock. It could come from either of the spouse but from whoever it is noticed, the other should not see it as the end of the tunnel. It is indeed a test of what marriage is known for, “for better, for worse”.

Inability to tolerate spouse’s weakness
Tolerating a spouse’s weakness means seeing that weakness as something that could be jointly overcome. The rationale behind it is whatever affects one affects the other. But when couples cannot tolerate each other’s weaknesses, and bear with one another, it escalates conflict.

Not affirming your spouse’s strength
When couples are unable to affirm each other’s success, display of talent both at home and outside, disagreement may set in.

Allowing a third party in your marriage
This is a very common phenomenon. Most couples confuse third party for a necessity in marriage especially mother in-law, father in-law, sister in-law and so on. It is not bad in itself for them to be part of the family but some couples go to the extent of engaging them in taking decisive part in their marriage. When couples do so, conflicts may set in.

Keeping secrets from your spouse
Secret in itself is not encouraged in marriage. It is an opposition to mutual and self-giving attribute of marriage. Most often, you see couples frowning at the attitudes of the other person for failure to know certain things which he or she should know such as bank accounts, friends, society or association a couple belong.

Inability to express feelings and emotions in marriage
This is also lack of communication. When it is not there, couples are unable to express their joys, sorrows, feelings and emotions verbally and non-verbally. In other words, couples are not free to show true love and affection to each other, which is a pointer to conflict.

Not respecting your spouse
Respect is reciprocal. So, when a spouse is not respecting the other, he or she other may tolerate it for some time but when patience runs out, the result is conflict.

Nagging attitude
Being a nagging spouse means that he or she is troublesome, problematic and someone that always causes trouble in marriage. It is an attitude that can trigger conflict and even violence.

Not trusting your spouse
Lack of trust brings about unnecessary suspicion by couples in marriages. Experiences show that not all suspicions are true and so many marriages have been ruined by lack of trust.

Discussing marital issues with outsiders
Some spouses frown at their partners’ attitude of discussing their marital issues with others especially when they get to know about it. It causes conflict.

Spouse’s support of a child’s misbehavior
Children are fruits of marriage and also gifts from God. There is this tendency for some couples having soft spot for a particular child. So, when such a child puts up a bad behavior, correcting this could cause conflict especially when one of the couples sees nothing bad in it.

Lack of patience
Marriage they say is not a bed of roses. When challenges come up such as childlessness or things not being rosy, patience could be sacrificed on the altar of aggressiveness. The after effect is conflict.
