I need others views

So cut a long story short I’m 28 and for years I can remember my dad emotionally and physically abusing my mum .

It’s been a normal up bringing and to be honest I’m scared of him and to confront him .

I have begged my mum to leave him . But because he has no friends because he’s not the nicest man and is aggressive he’s lost them and pushed himself away .

He emotionally makes her feel guilty for things and hers fixated on something and will blow it up and my mum will say the wrong thing and he screams aggressively .

Last week he hit her ! She didn’t tell me I asked her over and over she promised it wasn’t him .

Turns out it was him. He smacked her strangled her and dragged her by the hair . This is not the first time he has done this.

My mum said on Friday because I didn’t come because I was mad with him he took it out on her. He strangled her she said she thought this was it she was going to die that this was her last breath.

He finally stopped and said omg we are going to kill each other what am I doing, he then pretend to have a heart arrack .

This weekend him and I fell out over something pathetic but he blows it up into something huge !

I left I asked if she would be ok.

Well apparently she wasn’t loyal enough to him in this situation he head butt the wall and actually made a hole in it.

He got a curtain pole and put it round the neck . He then shoved it down his throat and said you want me dead!

He went through himself from the top of stairs, she followed he through a chair and she finally ran . She was hiding in grave yard scared he would find her.

After 29 years. She told us all the truth the things he has done.

We rang the police because my family was disgusted and said it’s what he needs we are also scared he would kill him self .

He got arrested and my mum and I feel sorry for him. He’s lost everything no family no job everyone hates him .

Am I crazy ? I went home and left money for when he got let out. When I gave a statement I left money with the police to give him to get home.

When he had his interview he admitted to some things but not all.

The officer told my mum he will he staying in prison over night until court today for the safety of my mother. He threatened her safety to the police.

Please someone tell me why I feel sorry and guilty for this man ! Should I of stopped my family ringing the police. Told him it’s over with my mom done it that way.

Now he’s in prison he could get sent down . He will hate us. We have done the ultimate betrayal.

If you read all of this thank you .

Think if this was your dad we have had some good times to. But I know what he’s done is wrong but have taken it to far with the police ???
