You'd think he would have learned his lesson after already having married one crazy b*tch from your family.

I'm surprised that no one (to my knowledge) pointed out that the divorce could be OPs fault? What if OP cheated on ex husband and the family loved ex husband and sister fell in love consoling heart broken ex husband? Were so quick to believe the OP, but we don't know the whole story.

Also, we don't know ages or anything. For all we know that divorce could have been 10-15 years ago. There is a bunch of key information missing, you can't make an accurate assumption.

sorry to say it but your sister is a low life bitch , how can any sister marry your ex, that pretty down right dirty , and very desperate , if I was you I would never speak to her ever again. I guess you can be happy that you didn't marry a jerk like that.

HA!

Wow that's really messed up. Never thought it was possible for a sister to be such a bitch.

My question is, what kind of sister is that?? :/

FYL. That sounds like my friends moms' life. That sucks. :(

what a dick!!!

If you and your sister had children with your ex, your children would be cousins and half-siblings with your sister's children. Also, your sister would be the aunt AND step-mother of your children. Sounds like Jerry Springer is needed.
