Well, it's now 2 months later, and I decided to give an update. My father's health is deteriorating quite quickly. He's been to the doctor, and now he has to wait a month for the catscan results. His breathing is lousy, he's become incredibly weak, and he has an incredibly difficult time getting out of bed (he woke up at 7:30pm on Saturday after going to bed Friday evening).
As far as the issues he has with me, nothing's changed. He offered me $5000 not to get married, and he's really pushing the issue. He told me the other day to get rid of my truck (because I've had to do some repairs on it). Honestly, me and my mother don't see him lasting much longer. The Doctor didn't give him anything, no pills, no inhaler, no time off work, nothing. The doctor told him to eat half as much as he is now (he's overweight) and to quit smoking.
My father seems to have given up on himself, and if that's the case, he deserves what he brings upon himself.
