Hello

It has been 2 years and over I have been with my girlfriend.

I am so emotionally exhausted .

days ago her daughter starts screaming at her mother then her mother screams back at her .
This has been going on for years her 21 year old daughter tried to commit suicide 3 times .
She was in a hospital for 2 weeks last time she tried to commit suicide .
But she refuses to see the psychiatrist.
Ive put up with so much with my girfriends family , the stories are a lot .its so hard .
I finally lost my temper and told the 21 year old daughter what I thought and her sister whom is
15 just closed the door on me .
I just can not finish the realtionship with her .I dont know why I can not say its finished .
Maybe .I dont want to be lonely . Maybe , I like to live like this .
I am so lost and looking for answers . please help anyone
