Woman Tells Sister The Shocking Truth About Her Husband, Never Imagined It Would Turn Against Her

Cheating is one of the most heart-breaking betrayals anyone can face. But what if you’re not the one being cheated on—just the one who discovers it? Do you step in and say something, or let things play out on their own?

One Redditor overheard her sister’s husband having what was clearly an affair. Believing she was doing the right thing, she told her sister. The truth led to a separation, but instead of blaming the husband, the rest of the family turned on her—accusing her of ruining the marriage by speaking up.

Now, she’s asking the internet how to deal with the pain of being blamed for her honesty. Read the full story below.

Why people cheat, according to experts

No one ever wants to be on the receiving end of cheating. Yet it happens more often than we’d like to think.

According to Statista, which looked at data collected over 50 years, around 21% of people admitted to cheating. That means many of us either know someone who has gone through it or have experienced it ourselves. It’s a deeply painful betrayal that can shake the very foundation of a relationship.

When infidelity comes to light, one of the first reactions is usually a flood of questions: Why did this happen? Why me? Why us?

The truth is, there isn’t just one answer. Based on a study published in the Journal of S*x & Marital Therapy, researchers identified eight common reasons people cheat: anger, low self-esteem, lack of love, low commitment, need for variety, neglect, sexual desire, and circumstances.

These motivations not only shaped why people strayed, but also how long the affair lasted, how emotionally invested they became, and whether the relationship survived.

In a piece for Brides, Lilly Blomquist explored these reasons further with the help of experts. Here’s what they had to say.

Anger

Some people turn to cheating out of anger at their partner. Rather than expressing their frustrations directly, they act out by seeking revenge through infidelity. In certain cases, one partner’s affair even prompts the other to do the same, hoping to inflict a similar kind of hurt.

Low self-esteem

According to licensed marriage and family therapist Courtney Glashow, those with low self-worth may cheat to feel more desirable. While the attention may provide a short-term lift, it usually deepens their feelings of inadequacy over time.

Lack of love

Falling out of love or feeling unloved can also push someone to seek connection with another person. While every relationship eventually moves past the honeymoon phase, some look for that passion again outside their partnership instead of accepting the change. This also applies to those who feel their partner no longer shows them affection, physically or emotionally.

Low commitment

If someone isn’t fully committed to their partner or the relationship itself, they’re more likely to cheat. A lack of investment can quickly turn into a wandering eye.

Need for variety

Relationships can lose some of their spark over time. While this is completely normal, some chase novelty with another partner in search of excitement and thrill.

Emotional neglect

A healthy relationship relies on both partners meeting each other’s emotional needs. “Whether it’s feeling undervalued, unsupported, or misunderstood, unmet emotional needs can drive someone to seek validation outside the relationship,” Glashow said.

Jeff Yoo, a licensed marriage and family therapist at Moment of Clarity Health Center, added that women are more likely to cheat when their emotional needs aren’t being met.

Sexual desire

Physical intimacy is another need that, if left unfulfilled, can drive someone toward infidelity. Yoo noted that men are more likely than women to cheat when there’s a lack of sexual satisfaction in their relationship.

Situation or circumstance

Sometimes, cheating happens simply because the opportunity presents itself. Glashow explained that this is common in long-distance relationships or when personal boundaries are weak. Relationship expert Kelly Campbell, PhD, added that people prone to infidelity may be especially vulnerable if they find themselves in compromising situations.

Once the “why” is clearer, the next question is: what now? For some, cheating is a dealbreaker, the final straw that ends the relationship. But for others, it can be a turning point. As couples therapist Naomi Light explained:

“If your partner truly regrets what has happened is willing to end the affair and you’re both prepared to put the work into finding your way back, there’s no reason why you can’t save your relationship.”

“Whatever the case, trying to examine the issues together is your best chance to make sense of things,” reminded Light. “The person who’s cheated will need to take responsibility for their own behavior as wrong and not make excuses.”
