Absolutely is no one else's business, I agree. But catch yourself on a bit. Did she care about Dominique's mental health and the dozen or so other women's while she was copping off with all their husbands and bf's?It's really no ones business who the woman is that her fiance chose to cheat with. She wasn't the one cheating and nore was she committed to anyone.
What about her mental health? She has had a very tough time but she didn't cheat on anyone.
She's a grown ass woman who behaved in a manner that reflects who she is. A one time thing? Bad form, but a horrible mistake. She has done this several times judging by Dom's stories. She was well aware of what she was doing. And she rightfully should be feeling crappy as it's clear now she has ruined one relationship and possibly many more. She needs some serious self reflection that's for sure.
Edit to add- takes two to tango. No blame lies on just one party in all this.
