I am trying to sell my house for 89k dollars, I have been in a bad financial situation, my nephew knows it, and now he is trying to buy my house just for 75k, trying to take advance of my situation
Wow, that's terrible. Why would he do that to you?
I have no idea, I guess his husband is evil 
I'm sorry you're having to go through that, I hope you're able to sell the home for a better price.
me too, and do you know what makes me mad?  When I had a good job, I helped them a lot, and now they are trying to do this to me
That's just terrible. Some people really are ungrateful.
I know, right? My own nephew trying to do this with me
Well, hopefully he'll learn to be a better person someday, or eventually his actions will come back to haunt him.
