To the guy who want to date his brother's ex.... We are not the right person to ask this question, your brother is the right person you need to talk to. Ask him the reason why he break up with the lady and if you see nothing wrong in his reply, ask him if you can date her.... All answers lies with your brother.... But in my own opinion... It isn't a good idea and I don't even think the lady would agree except she has got a motive.. And there is a saying, never go back to your ex, your brother ex is somehow your ex too, lol, blood is thicker than water.... Be wise
