Reporting about narcissist wife to home office

[shor]

Hi ,

I am have been struck in complex situation.i Hope someone will guide me or suggest .

Please bear if the details are long trying to put my pain in few words

I married in aug 2016 in india and however later i realised my wife is narcissist .
She has been telling lies and made sure i have less contacts with family and friends .
I have realised she was married earlier and was with her ex for almost 7 years
however she lied and told me it was short marriage of 3 months and never registered.
Hence she had put in visa application that she is not married ( this is visa Fraud However i am scared to complaint
as she threatened me ). Later once in here she has been abusive and threatening .Though i initially felt i was not making her happy
and was trying to make her happy .Later realised she was doing to all this intentionally. On my back she has
cut down my friends and where she has been telling lies to them about me being abusive .
In May One day we had argument and she went to police and said i have abusive to her and where as she
was the one who is abusive of me and physically hitting me and i was trying to avoid her hands .
I was give non molestation order .Once back home she was normal for few days.However Now she is abusive and threats almost every other day.

She threatens me that i can do anything i have social charity numbers and She in contact with them
occasionally and says i am abusive where as she does that.She mentions Social Charity
told i can file a case on you however she is not doing it .She abusive and forces me to give divorce and she says legally you have provide me everything .And Propagating lies to my friends and relatives back in india that my family in india is threatening her. Where as they are scared to
do any thing as she threatened if anything i will complain here in UK .

I am not able to trigger a divorce as i am have invested all my earning i had in purchasing the flat and now she wanted property on her name if plan to divorce.She is more qualified however she is not ready do any job.

I feel like running away from home still fear that she might again start a complaint chain i deserted or she might go to social charities that i am not giving her any maintenance .

If i report to Homeoffice do they take any action on her for being having told wrong information to home office about marriage. But fearfully that she might trigger
the cases as she threatened earlier with help of social charity .

Please suggest
