I don't think IABU, I really just need some advice. The relationships board might be a more appropriate spot, but I'm posting here in the hope that you all will give it to me straight.
My father is coming over to my place today (not in UK, it's mid morning here), and I'm worried about it.
Dad has a history of being a bit of an arsehole. He's quite controlling and still often speaks to all his children (who range in age from mid 20s to mid 40s) as though they're 10. Actually, it's worse than that - he can be quite abusive both physically (although not for 10 years or so) and certainly emotionally/mentally (yelling, namecalling, belittling). We generally all stand up to him, although it's exhausting. He's quite verbally abusive to my Mum though and I think she's scared of him.
Last time he was here (we can have 2 people who aren't members of our current household to visit as long as we stay 1.5 metres from each other at all times) he decided he was going to do some DIY on our house. I told him it wasn't necessary and he insisted. I caved because it was easier than having an argument with him - he gets quite cross if he offers help and any of his children refuse it. I think it's a form of controlling behaviour. (He always does a shit job too, but that's another story).
So he rang late yesterday afternoon and announced he'd be coming over today to do this work. I said OK. And now I'm really nervous and cannot work. I'm usually OK when he visits - I think it's because I'm here by myself with only the children as DH had to go into work today.
Last time he did any work at my house was about 2 years ago. He always gets angry when he works with others. This particular day day was pretty standard - he gradually got angrier and angrier, until he yelled and told me to 'bloody hurry up' because I didn't move a power cord quickly enough. I stood up to him and told him very firmly not to speak to me like that. He then got right up in my face and yelled into my face with such vitriol, and called me a "fucking bitch" amongst other delightful things. I told him he would have to leave if he couldn't behave. He backed down, went for a walk to cool off, then came back calm and said 'Well, we had a fight". I said words to the effect of 'Yes, and you behaved badly, and if you ever behave like that again you won''t be welcome here". He didn't say sorry. He muttered something or another then went back outside to finish the job. Then he left. He, as always, pretended nothing had happened. (For background - he never ever acknowledges that it is his fault, ever. These kind of altercations happened weekly when I was a child and very often escalated into violence and I had bruises/black eyes maybe once a year from it and he still almost never said sorry. On one occasion when he had punched me repeatedly, slapped my face, and dragged me about 3 metres on the ground by my hair, I didn't speak to him for 3 days. He then said "I've been feeling sick about this for 3 days. I shouldn't have hit you, but you make me so mad - more mad than anyone else does. Now give me a cuddle and let's put this behind us" or words to that effect. Then he pretended nothing had happened. I was 11 or 12 at the time. He has since claimed he 'can't remember' doing any of those things. My mum and brother saw him, so he actually did do them. He has also pulled me off a horse then kicked me while I was on the ground and told me to stop snivelling like a dog. He's also denied doing that. So he's not nice).
I was pretty low contact with him for a year or so after this experience while working with him, including because he started being mean to my daughters including about their weight so I reduced contact. He was a lot better for a while, but in January he came to the house again and flipped out because one of my nephews (I'll call him Jay) couldn't get his boots off to come inside for lunch so he told Jay that Jay wasn't allowed to have any lunch. I told Dad not to be so ridiculous, that it was my house and I didn't care if Jay came inside with his boots on and that Jay would be getting lunch regardless. Cue what I can only describe as a tantrum from Dad - stomping around, raising his voice, and lots of passive aggressive comments said in a loud sarcastic voice ('Fine", "Well you should do what you want" "What I think doesn't matter' and the like). This behaviour is very common for Dad. I stood up to him, and told him to 'Just stop it' and treated him a bit like a toddler having a tantrum. This was quite effective and seemed to shut Dad up. Jay got lunch in the end and Dad sulked for about an hour - he went downstairs to 'discuss' my behaviour with my mother and I could hear him whispering at her that 'She can't speak to me like that' and "She should have dealt with that differently" and various other things (My poor mum - he did this where I could hear on purpose I suspect. He bullies her too.).
Anyway, he's coming round today and I'm worried. I've gained a bit of weight during isolation and this always annoys him - he doesn't say anything but he will look me up and down repeatedly or stare at my fat bits with a look on his face like he smells something bad. It makes him more picky about other things too. I guess the fact I've gained weight makes me worried he's more likely to be angry and to become abusive.
So yes, I know he's an arsehole. I stand up to him pretty firmly these days - I'm reasonably tough and am used to dealing with arseholes at work. I used to get upset and cry, now I just get angry (it's taken years, I'm in my 40s). I'm happy to kick him out if he's being a twat, I've done it before. I don't know why I'm so bothered by this today. I think maybe because the last time he did work here he was so abusive and it really upset me, and today I'm by myself. Or maybe because I actually didn't want him to do the work in the first place but agreed anyway - so I feel on the back foot.
So any strategies you can suggest? Last time, speaking to him like an adult having a childish tantrum worked (except then he berated Mum instead of me - I feel terrible about that especially as I didn't step in, but she gets upset if we intervene), so I'm thinking I might do that again (eg in a firm voice 'Stop that please', "That is not a helpful way to behave", 'Don't speak like that please', 'Do you need a break to calm down?'). I think that worked last time as I didn't show any fear at all - once he sees fear he's like a shark who smells blood. But does anyone have any other suggestions?
Apologies for the word vomit, I'm actually a bit beside myself which is unusual.
