I found myself in a very annoying situation.

I recently (within 1.5 years) moved from my country of Origin to the country where my partner lives. She has two daughters who's Dad is "absent" and has been for many years.

I moved in before Covid and all was well. Covid came along and lock downs etc and this is where the issues started.

Both me and my partner work, the two, call them SC are 19 and 21 year old are both students. They decided that one should be upstairs studying quiet while the other was downstairs listening to loud music. I return from work extremely tired and need some time of my own.....but no they won't give this to me as it's their "rights" to "own the house" my partner will not intervene as she believes we should "communicate". The problem is we communicate but it's one sided they change for a week max then business as usual, back to the old ways. 

An unfortunate recent turn of events was me over hearing a conversation between the eldest step daughter and her boyfriend stating very clearly she wanted me gone. I told my partner, for a number of reasons she believed me. She confronted her daughter who has twice denied this comment. 

We both never believed she was capable of lies like this but sadly it appears she is. 

Am I being stupid in assuming all the toxic atmosphere in the house was planned by them both to remove me so they could have their happy life care free all paid for by mummy back?

I find myself faced with two realistic choices 

1 move out and stay in the country where I am as I have a job here and all my residency permits etc etc.

2 I just say forget it and leave and return to my home country where my two kids are living with my ex wife.

I am abit stuck and struggling to find a way. Every time I try the two stepdaughters always "justify" their malicious ways. It now pretty much unbearable and I no longer talk to either.
