Boyfriend's bro a big no-no

What's a girl to do when she feels the urge to stray - and the guy in her sights is her fella's brother?
That's the dilemma that faces MY Sun user lksss, and she needs our advice.

"This guy is really nice and sweet ... but I just get on better with his brother," she explained. "They live together and his brother always comes out with us or I manage to bump in to him in the club ... I have no idea what to do. Help!"

Is it wrong to dump a fantastic fella for a little bro-mance? Users chewed this over on our Woman forum, reports The Sun.

When it comes to voicing opinions, emmaquantrell never minces her words: "I think you are a very selfish girl ... you should never start seeing the brother: that will cut your fella deep!"

trublu however, takes a more sympathetic stand: "I wouldn't say she is selfish emma, as she's asking for advice, as stated in the Sun

"If she went ahead and got with the brother, then yes, selfish as hell."

So is it okay to go for the bro, or is that just breaking branches from the family tree?
