ok so i have 2 beautiful kids one boy (15 months old) and 4 yrs old. I am currently living with my daughters dad ( my EX husband). i have no where else to go but the verbal abuse and mental abuse is just so unbearable. like im gone all day till night so the kids dnt gotta deal with it. But its getting so bad idk what to do anymore. He thinks we are together and yes i still love him but im not in love with him. he is very emotional and yes very ill. what should i do? he is practically on his death bed. help anyone?!?!?
