I'm done with my stepbrother.
What did he do this time?
He just is a big jerk
It is often challenging to get along with siblings and step-siblings. But, family is almost always going to be a part of your life, so you need to find a way to get along. You don't have to be best friends, just be polite.
I'm tired of him. Like most people with siblings, we are better left out of one another's lives.
I do not think that that is always the case. I think that it is good to get a long with your stepsiblings. It makes life easier on everyone when you just get a long.
