Fate, although I have never met you, I can tell you are a good man. Keep strong, and like others have said, let the mom thing slide off. Every family has issues. Some families are full of rational people that can communicate and act rationally. Other families have members that refuse to see the truth or reality and it becomes very very difficult to try and deal with things with them. (this is my case as well) In your heart, when you know you have done the best you can to resolve such issues, but the issues are still somewhat unresolved, you can walk away knowing you did everything you could to help correct the situation. Those family members who are only in it for certain things which benefit themselves will not be able to do the same. You have done all that you could, and probably even more. You have nothing to be ashamed about. Others down the road may realize how selfish and foolish they were. You did many things for your grandparents and that is admirable. I am sure your grandfather is looking down on you right this very minute smiling from ear to ear because he knows that you may not be talking right to him for comfort and help and guidance, but he is still sending it down to you and you are making the best of it. You will have great success with your business plans. Stay motivated. Be strong. Keep your head up. Great things are coming your way. Good luck with everything bro.
