Now I'm trying to get into a relationship, but...

My brother has been the dumpee...AGAIN!

All I know is that I was The Dumper, since I dated a slut at one point to proove that what a Gentleman I can be...but she chose the ******* over the gentleman (I know...nice guys finish last) but now that's my cousin...I won't date her...but I'm talkin' to a girl.

What should I say to my brother who has been the Dumpee? (The woman he was with wasn't a Gold-Digger...unlike the last person she was with...and I STILL say "She's Dead To Me"...though she's Catholic and since being Catholic...it STILL counts being a Christian)...what should I do?
