What are the chances my brothers relationship lasts?

Sounds like she's his rebound girl

You sound like a cunt. It's his life. Let him live it in peace.

So he's rebounding with a mentally handicapped person who has a personality that's the complete opposite of his ex? Yeah, it's not going to work.

Hang on, I have my crystal ball around here somewhere. If they're happy just leave them be, it'll either work out or it won't.

Hard to say. She may feel deliciously slutty to him in bed. If so, big problems will start when the rebound is over.

You're probably exxagerating the inappropriate things.

Anyway, you don't know his ex like he does. She might've appeared sweet but she could've been abusive or horrible to him for all you know.

Anyway, I think you should let them be. They're obviously happy, don't be destructive.

Guaranteed break up as soon as he realizes she is nuts.

Don’t worry about your brother. He chose to be with her, therefore, there’s no reason for u to be concerned. Just be grateful you’re not in a relationship with a chick like that :p

Nobody here can possibly know if they're going to break up or not.

You clearly don't like here, but it's his life and he has the right to spend time with whatever woman he chooses.

Bear in mind that some people stick together largely because their families openly disapprove. Sometimes, that's just a phase of growing up where people feel the need to prove to themselves and their families that they are independent people. Sometimes, the family opposition provides a common enemy which helps the couple bond, whereas if the family was indifferent or supportive, the couple would be able to focus more on each other and see more clearly the failings of the other person.

What would be an example of something inappropriate to laugh at, I'm curious.
