Why Frank hated Paddy so much when he found out Fee was pregnant again?

[Sandy]

Paddy was Fee's husband, wasn't he?

What kind of love was it between Fee and Frank?

[Kandice]

Frank just felt that his mother worked too hard and was too old to exert the energy needed to raise yet another baby. He felt that if Paddy couldn't "leave her alone" he should at least have been careful enough to prevent another pregnancy.

There was nothing incestuous meant or implied.

But how to understand the following paragraphs?
=====
And her face, her
beautiful tired face with its prim halo of golden hair, all alight
because of what she and that hairy old goat had done in the terrible
heat of summer.
He could not get away from it, he could not get away from her,
from the thoughts at the back of his mind, from the hungers natural
to his age and manhood. Mostly he managed to push it all below
consciousness, but when she flaunted tangible evidence of her lust
before his eyes, threw her mysterious activity with that lecherous
old beast in his very teeth .... How could he think of it, how could
he consent to it, how could he bear it? He wanted to be able to think
of her as totally holy, pure and untainted as the Blessed Mother, a
being who was above such things though all her sisters throughout
the world be guilty of it. To see her proving his concept of her
wrong was the road to madness. It had become necessary to his
sanity to imagine that she lay with that ugly old man in perfect chasitity,
to have a place to sleep, but that in the night they never turned
toward each other, or touched. Oh, God!
=====

It was not because Fee was old, it was not because Paddy wasn't CAREFUL either.
Frank wanted Paddy and Fee never turned toward each other, or touched in the bed!

I don't understand why Fee told Frand to have a wife just so that Frank wouldn't have time to think of her......

"But you need a wife, Frank. If you had one, you wouldn't have time to think about me."

I think it's because like he said, he wanted to imagine her as pure, he didn't wanted to imagine his mother having sex with a man he hated.
He idolized his mother and wanted to hold her up as someone without sin.

Most of us don't want to imagine our parents having sex, but with Frank it's an even more complex issue due to his feelings for Paddy.
He thought of his mother as this wonderful, flawless creature and didn't want his image soiled with the picture of a man he despised having sex with her.
Although Frank didn't yet know that Paddy wasn't his father, he probably suspected it and probably felt towards him like a hated stepfather.
I would assume some people would feel similarly if their mother started sleeping with a new man they didn't exactly love.

Plus, as said above, he didn't want her to have to go through the danger and rigors of child birth again.

Fee thought if he had a wife he would have something else to concentrate on, his own life.

Euraylie said it better than me. :)

[Sandy]

Thanks Euraylie and Kandice. That makes sense. :)

Somehow I don't quite like Fee and Frank, it looks to me, that they suffered a lot, but it was all caused by themselves.

Why couldn't they face the reality and be kind to Paddy? Why couldn't they have a grateful heart?

Can I say, Fee ruined her own life, she ruined Maggie's life too?

Very true! Good point! Frank imagined her mother as a pure woman and couldn't accept the fact that she had sex with a man he hated..Frank never loved Paddy and that's why he hated Paddy when he found out Fee was pregnant again.I think he didn't solve his oedipus complex..It is sad because Paddy was a hardworking man and tried to like Frank but Frank never gave him a chance...Frank just wanted his mother for him..like a couple.
