*very long angry rant*

I’m getting so god damn fed up of my dads behaviours and attitude, I’ve had the utmost respect I could ever have for him as a human being, going through cancer, domestic abuse and violence with my mother almost 2 decades ago and he’s currently had his last treatments on the secondary cancer he’s got (hopefully gone) and I became his carer three years ago but within the last year he’s absolutely disgraced me behaviourally and attitude wise.

He started smoking 6 ish months or so ago and it was resin, wasn’t happy about it as he still was in remission for his first cancer but accepted that cancer patients use it for pain or so he actually said it was for. He then moved on to actual cannabis 3 months ago and smokes it so much that he’s turned into a meat head, narcissistic asshole. then found out he actually just smokes because he’s depressed a woman whose half his age doesn’t want to be with him. Not from pain at all.

He works out 2-3 times a day at home and sun bathes for hours and hours!!! Neglecting all the household chores to the point the house is actually the most disgusting it’s ever been in my whole life living, he said two weeks ago he’d mop the floors, not done it, two days ago he said he’d do the cat litter, not done and it had the most rancid smell coming from it (poor cat 😓) and as a pregnant woman I’m not exactly supposed to be cleaning it, he whinges and whines about doing the washing up yet never does it properly and he made me put the washing out two days ago and it’s been on the line two nights in a row not brought in. But he spent today sunbathing for hours and worked out, came in and did nothing but smoke. The house smells like bio and dog shite because of the weed, yeah he actually smokes in the house whilst I’m pregnant. How fucking nice and considerate. How am I going to cope with this heavily pregnant when he’s more than adequate to do things but won’t? That’s not even half of it as well 😓
