It depends on why he's being jealous. Sometimes it's actually VERY cute & sweet that he's jealous,but other times; Does he even trust his girl enough? So if a guy gets jealous and makes his girlfriend question whether or not he actually trusts her...that's when she might get pissed.

In my opinion, of course it is. It depends, maybe this teenager can't find anybody whom he/she find interesting to be friends with.

Like? I don't think they LIKE to get beaten,nobody likes to get beaten up. These girls need help and they're probably lost and confused,'cause most of them think they'll never find a "better" guy. Unfortunately,what they don't know is that..A guy that beats up his girl is worthless and needs to be punished! :)

I actually think some people look absolutely cute with braces on =D
