Woman asks if she's wrong to not attend half-sister's wedding if the mom is there.

In situations with infidelity involved, you're supposed to be maddest at the person who cheated. That's the general rule, at least.

A woman recently took to Reddit to ask if she was wrong for not wanting to attend her half-sister's wedding, on account of the sister's mom being there. Her half-sister was the product of an affair between her dad and another woman. And she thinks her family would still be intact if the half-sister was never born.

She published the story under the heading, "[Am I the a-hole] for admitting to my half-sibling that I don't love them enough?" Uhh, way harsh, Tai. The full story is a little more nuanced than that...

The woman explains her family situation:

I (33f) have a three older siblings (37m, 35f, 35m) and a half-sister "Laura" (24f). My dad cheated on my mom and that's how Laura came to be. My mom was understandably hurt when she found out about the cheating and was willing forgive my dad and stay married until she found out about Laura.
