Ok guys need your help!

I could trade Dirtbag father stories with you all day long but the good thing is is will never be like that with our kids...
My dad has been sober for 30 years and I still have to treat him like a seven-year-old. Or at least process what he says as if he was seven. Keeping at least a thousand miles away has helped..
My father was a decent parent when I was a kid he wasnt around much he wasnt the nurturing type he was strictly the enforcer and the bread winner which I can respect that whatever. It wasnt until I got older things began to change and it maybe the older I got the wiser I got and I could see thru his bullshit idk? But he is a alcoholic and he had quite drinking for close to 15 years and started again around 2005. I think I have mentioned it but I too am an recovering alcoholic (31/2 years sober) well in 2005 I was at my drinking height so I thought it was cool drinking with my old man. The difference was when I got drunk I wanted to set at home eating pizza and watching TV. He wanted to argue and fight. He is an extremely hot tempered jealous envious petty person. So about four years ago I started seeing changes and some stuff happened between him and my mom and around that time I was getting clean. After I got clean I made it clear I didnt want to be around it and I didn't want my family around it. And he just couldn't accept that and he would come to family functions drunk off his *** and I kept my mouth shut and ignored it. Then last year things got really bad and my mom left him. I told them both I didnt want to be around him I didnt want my kids around him. And all was good for about 6 months and then my mom went back to him. So for the last six months i havent seen my mom and my mom hasn't seen my kids. I still talk to them both I talked to my dad on the phone for almost an hour the day before this whole blow up. Then the next day (drunk I'm assuming) he calls my wife and tells her off and says I should leave her and all this stuff because him and my mom havent seen the kids in a year bla bla bla. So I call him back and tell him don't talk to my wife she had nothing with her. Well he takes sends me a text saying that I'm nothing but a freeloader and he gave everything to me. It's just childish crap because I'm not giving in and giving him his way. So be it. I ain't never got nothing i didnt earn. Except for the land I live on and it was given to me my my grandfather. It was my wedding gift. He gave me and my brothers and my dad all land. My brothers was smart and sold theirs and moved away.
Literally everything my dad has was giving to him by my grandfather. The land he lives on the house this land where I live every thing. But I'm the freeloader .
