Should you still be friends with a girl if she went out with your brother one week after you broke up with her?

I'm proud of you for asking the board about this question. It may seem odd to you right now that she's dating your brother, but you both broke up for your own personal reasons and she can date who she wants and so can your brother. It's best to be pleasant to her, and you continue on with your life and go out with friends, and eventually you'll have another girlfriend and all of this won't matter. Take it slow and easy and if it upsets you right now, just try to stay clear of the situation if she's at your house. If you have to be there just smile and be pleasant and you can always get up and leave or go up to your room for some privacy. No woman (or man) is worth breaking up a family or friendship. Good luck Marcy
