how could you fix a ruined family?

I think that pretty much any marriage could be fixed if both people really want to. If one person wants to and the other person doesn't, it won't work out. I'm very sorry for what happened. I know that it is hard to think of your parents as being divorced/separated, but leave that up to them. Be careful not to get into their relationship too much. I know it will be very, very hard, but it's best if they can deal with it on their own at the beginning. If they have a long talk and decide that they want to work things out, they will need to get some counseling. That's the main thing. No matter what anyone thinks, they can't mend the relationship on their own. Maybe even family counseling after they get marriage counseling. That way you are all on the same page about everything and you'll have a safe environment to let out your feelings. If they decide after they talk that they want to go their separate ways, just know that it's in no way your fault and has nothing to do with their love for you. Again, I'm so sorry that this has happened. Hang in there!
