People cheat ALL THE TIME. If you say you have not, chances are you are wrong, depending on the vows taken.
If you promised to love, and care more about your happiness, security, safety, and needs than those of your spouse you have cheated the other out of what you promised.
If you promised to cherish, and have pushed away, you have cheated your spouse out of what you promised.
If you promised to hold, but refused comfort when they need it, you have cheated your spouse out of what you promised.
If you promised to forsake all others, yet spend more time with your friends than your mate, you have cheated your spouse out of what you promised.
Seems to me; the ONLY vow-broken that matters to MOST people is the 'forsake all others', within a sexual context. I wonder why that is? I hold my wife to every vow she made; yet hold myself to not only my vows, but the intent of a marriage in the first place.
Further seems-to-me: A body can avoid Loving, Cherishing, and otherwise doing GOODNESS to their spouse...then, sure as shit, they Pull out the Victim Card quicker than WindSong in EVERY THREAD SHE'S IN, and claim "My spouse CHEATED on me! He/She had sex with another woman! (gasp!)"
No, friend - your spouse didn't CHEAT on you...you left them NO place for intimacy; love. Another person offered them the MOST-IMPORTANT aspect of a relationship...the sex they had was likely the result of the other person meeting the intellectual/heart-needs.
Course - sometimes...a spouse just wants a piece of tail from another participant. In that case, the one having sex was cheating LONG before they had the sex.
WS, you aren't married. You are living with somebody (allegedly) of your gender. You don't have a wife. You (allegedly) have a sex partner of your gender with whom you fornicate. You have somebody (allegedly) of your gender you share your life with. That's NOT a wife. You are not a wife. You never will be a wife if you continue your choice of lifestyle.
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
