Even if you are married to the best spouse in the whole world, if you do not guard your heart, you may end up "falling in love" with someone aside from your spouse and eventually ruin your marriage.
No one gets married and plans to have an affair but lots of married men and women are into affairs today because they slept when they should have been wide awake with their five senses alert.
Don't be too friendly with the opposite sex. This is where lots of married people land in trouble. Over spirituality and pride will destroy your marriage! You can't handle a close friendship with the opposite sex as a married person. Your heart is involved. Set boundaries. Be disciplined. Be cordial. Be respectful. Be godly. Be holy.
Don't share your personal problems with an opposite-sex friend. It will bond you together. Problems bond people.
Don't contact any opposite sex you are fond of. If you secretly admire them, you are fond of them and there is a tingling in your heart at the mere thought of them, don't contact!
Avoid unnecessary eye contact that lingers with the opposite sex.
Don't tell opposite sex you are romantic or sexy, that private information is for your spouse only.
Avoid discussions with the opposite sex when you are tired, very sad, depressed, sorrowful, drowsy, sleepy or very sick. This can cloud your judgment and make you say silly things. Talk to your husband/wife instead.
Avoid unnecessary compliment of the opposite sex.
Stop saying "I love you" to the opposite sex, for what?
Work on your marriage. Keep the fire of love and romance alive in your marriage!
Protect your family. Don't share your marital problem with your opposite-sex friend, it will bond you.
Never flirt with the opposite sex.
Mind the pictures you post on social media. Limit pictures that show your curves or portray you as sexy.
Do not contact all your EX after marriage.
Don't chat with the opposite sex on the days you are horny.
Stop focusing on your spouse's weaknesses and appreciate their strengths. If you always see the bad side of your spouse, you will be angry, bitter, critical and look for someone who can "understand" you and make you happy aside your spouse, that is the beginning of an emotional affair and eventual sexual affair. It is the beginning of the end of a once glorious marriage!
FLEE from all appearance of evil is what the Bible says.
What you will not eat, don't bring it to your nose, don't smell it!
Don't start what you cannot finish!
