The biggest reason for women staying with cheaters is low self-esteem.
Whenever you believe you can't do better than the man you're with, or that your happiness depends on him staying or leaving, then you'll always lie to yourself.
A few things to notice in the video:
1. Notice how she tries to downplay cheating: When a man cheats on a woman and the woman has low self esteem, she'll change the narrative from "kissing is cheating" to "it's just a kiss, it's no big deal". What she's doing here is looking for justification to stay with him. She's rationalizing her decision making. What happens from this point on is that she will be the type of woman who's easily lied to. She's asking for it. She doesn't want to know the truth, even if it's staring at her.
2. Notice how, at the end, she wasn't happy about finding out the truth. She said that it was a big mistake. Why? Because maybe she's had a feeling of how he really is and it's confirmation. She went in NEEDING a certain answer. She wasn't looking for the truth, she just wants to be happy and if lying to herself makes her happy, then she'll lie to herself all day long.
Don't find yourself in this situation. Be rational. Go into relationships skeptical. Notice your inner voice wanting things to work out. Notice yourself lying to yourself. Notice all those little things. You don't have to do anything about them, just notice. Don't let those thoughts and emotions remain unconscious. Bring them into conscious awareness.
If you want to change your husband and/or boyfriend, from a cheater to a loyal one, you can't do that. There's nothing you can do to change them completely. You either leave and let life change them or you stay and deal with it. There's no middle ground.
