T/W Brother ended his life

My brother took his own life.
He shielded me from his intentions to do so. He had a very unhappy marriage and was a victim of domestic abuse.
I did everything I could with the limited knowledge I had. He took his own life because of her and her family. They clearly are not grieving. She keeps telling everyone how his last 4 months were hell for her. she knew what he was going to do and she didn't stop him.

I wish he had confided in me.
I don't want to be here. I want to be with him.
His wife is trying to cause me to lose my job because my brother was reliant on sleeping tablets which he purchased himself for a long time. he told me he was coping well however his wife kept binning them. He asked me if he could send some to mine. He reassured me he was doing well so i saw no harm. I did eventually put a stop to this as he kept telling me she was binning them and wanted to order more. Alarm bells rang and i refused. he said that was fine and seemed to be ok. we talked almost every day. /i went on holiday and he was phoning and texting me with general chat. He genuinely seemed ok. When i came back from holiday we arranged to meet up and he was excited to show me his new laptop and get some cake. that same day his wife called me to say he ended himself. That they had a massive fight and he went into an episode of "mania" and went into the garage. His wife said she was aware he wanted to go into the garage to end himself and told him not to. She left to see their 6 month old child knowing he was in a state. our father lives 2 mins away. why didn't she phone him like she did with every argument. why did she call someone to come and help who lives 15 mins away and when they arrived THEN she decided to call the police?
She illegally obtained his phone and found he had sent 4 orders to my home. She is aware I didn't do anything illegal but is trying to "come for my job."
I never did anything to hurt my brother. I don't speak to my mother or his wife due to previous issues so im not surprised she is doing this.
My brother took his own life because of her and her family.
I'm stuck.
I'm 12 weeks pregnant and have 2 kids. I don't want to have to deal with this. I didn't do anything wrong.
I'm usually a strong individual but I have not grieved for my brother. I've not had the chance and now I'm faced with this.
I'm so lost.

I'm so sorry for your profound loss

Condolences @Kada33...

I encourage you to:

1. Get professional help...

2. Cut off all contact with family while you sort things out.

I've been where you are and am so happy I didn't succeed.

It took a while to sort it all out, but you've done the right thing by reaching out.

I'll share a mantra with you that also helped me as I worked through it...

I'll be damned if I'll give the bastards that!

That being my life!

Please don't give them that, they've already done enough damage, and you are correct...

You've done nothing wrong!

Thank you.
I know i didn't do anything wrong.
However they try there best to point a finger.
He struggled with his home life and was very unhappy.
I've contacted a lawyer to see if there is anything I can do.
I won't let them win.
I need justice for my brother.
It's just hard when the brain kicks in and makes you feel hopeless and worthless x

It is hard @Kada33, but...

You've done the right thing by contacting professionals that can help you navigate the difficulties!

I'm in your corner and pulling for you...

I’m so sorry. That’s a Hugh loss.

Thank you,
I appreciate your support.
It's just such a horrible time and I'm not sure whether I'm coming or going!
I've contacted the police who have confirmed I've not done anything wrong. They haveaso said uts not a police matter and I should seek help from a lawyer so it's monday before I see him x

I'm so happy the police have offered you peace of mind...

I'm also glad that you've gotten an attorney to help you sort things out.

Maybe he'll be able to fix it so they have to stop interfering with you and your job...

You need to be allowed to grieve without them trying to cause further trauma and harm!

Family can sure be ugly sometimes...
