You can buy back in to most games, you can buy in to the next upcoming tourney.
Can you buy back in to your family?
You can pick your nose, and you can pick your friends but you cant pick your family.
It all depends on you, but I put my family first. Of course, I have a family I love, and children, so I view things from all sides. As a father, as a son, as a sibling.
If your expectations about poker are unrealistic, you may not see that, whereas a family member who cares about you may. So if you get flak, it may be coming from someone caring about you.
I had a brother (he is still alive, but had is correct) who did some shit that cant be forgiven. He no longer has a family. I aint talking poker here. He is a sad human being.
Dont forsake your family, cause it may not be reversible.
If you play poker anyway against their wishes, I think that is absolutely ok if your have realistic expectations. Which I do not believe you do. If you lose, dont ask anyone to help you out financially. If you do this, its yours. You break it, you fix it.
