Family ties with homosexuals and those living in zinna

If I condone such, will I be answerable to Allah SWT on the day of Qiyaamah?
I have been avoiding any form of direct dialogue with them thus far, as she, my homosexual cousin is rather troublesome too. She claims to have direct contact with the marhooms and that she can foresee the future.
Please treat this with strictest of confidence as I do not want my family to be publicly ridiculed or humiliated.
Please answer in detail as most Muftis would give monosyllabic answers without any explanation.
JazakAllah Kair.
