I agree with seesaw that you would benefit from therapy.

Unfortunately you have strained relationship with your kids and one of the reason could be unrealistic expectations of them: wanting them to support fraudulent things like filing taxes or getting driver license fraudulently, wanting them to listen to your speaking poorly about their dad or wanting them to like random men you meet etc etc Most adult kids wouldn’t support any of it as none of is appropriate.

I think I’d really focus on understanding reasonable parental expectations of adult children and improving your relationship with them
