What the fuck was Edith's problem?

What the fuck was Edith's problem?

She had a lot of mental problems, probably depressed and/or schizophrenic and definitely had post partum depression.

Did you not actually read the book or are you just as autistic as Stoner?

This, because her father had molested her when she was a child.

Fill me in on the apparent Affair Edith had.
I assumed she would always have one but it was never clearly pointed out desu.

I thought he was going to get cucked by that annoying cripple

Same.
Thought it was actually gonna have a hilarious part to it, but no....

I was hoping for some finch on stoner hot steamy action.

emotionally repressed, married to a man she didn't know at a young age

I thought she was sleeping with Lomax because of the long kiss at the party and that she was somehow always aware of Stoner's personal issues. I'm not sure if this was intended or I read too much into it.

Is there any evidence of this in the text?
