the terror felt and the lies that she must have fed him. It reads like a horror-story! I guess for some men, it's drugs and/or alcohol, for others, the addiction to a partner. I remember flashes of my father's sense of humor, the struggle to say he loved us, [because he wasn't loved himself as a child]. I only heard him say "I love you once or twice and then it was when I was an adult.
I think that you should switch the first and second verse around. Did you mean "the moments intents" or the the moments [intense]? I would go with "I swallowed [the] pain. "My father, [dead] three years now" "I never had closure, [in] these events.
Just a few little changes to make the piece a little smoother. Of course, if you have better ideas or want to ignore my advice, it's your work and no one will find fault. We try hard to see the writer's vision and sometimes I miss. ~ Geezer.

When a dad who was everything later changed to be a monster against his children must have been influenced by someone else who was sharing mutual trust with.

I truly believed what Geezer's said. Someone who was closer to him fed him up with series of lies and that's why he capitalized on what he was told.

Take a look at the corrections he has given you and change them as soon as possible.

you already have some good advice. I will tell what I think, too. to begin with:

Manifestation of thoughts of (the) suicide and hate (remove the) I am sorry that he believed such lies, it must have hurt you dreadfully! (my Dad was my hero all my life) my mother was the monster. the most extraordinary lines are:

My father died three years now
And closure was never met, of these events
It remains a wound to those who knew
Memories hid by only a few
It will always linger and resurface when I think of my father as the parent he was.

I don't completely understand your situation because; my mother never loved me. she hated me from the start of her pregnancy. but Dad balanced it out. I know what it is to go without closure and I am so sorry.
if I were you, i would give this poem a snappier title, like (Trials with Father) or something of that order. the body of the poem is good, it tells of a tragic tale. one which is very well told. the start and ending are satisfying. most poignant lines are these:

My father died three years now
And closure was never met, of these events
It remains a wound to those who knew
Memories hid by only a few
It will always linger and resurface when I think of my father as the parent he was.

keep on writing... you are good at it!

I’m imagining the process of writing this was intense. I have a multitude of empathy for you. Your willingness to pour all that trauma onto the page is miraculous and beautiful. I’m misty eyed. I’ve no suggestions for edits but you moved me with this piece. It is an emotional nightmare that I’m truly sorry you experienced. You are a great writer and I hope the process of writing this helped to process and validate some of these feelings you’re carrying around. Very powerful.

Walk again in the light,
