So, I must be psychic, because I remember saying that I was afraid the next move up SD21's dirty sleeve would be her getting pregnant. Well, it happened. 

She accidentally let it slip when explaining why her boyfriend wasn't at work when DH stopped by to say hi. She found out she was pregnant and got an abortion. Her BF had to miss work to stay with her after.  Worse, BM, SD17, SD19 and pretty much the entire BM family knew about this, but no one told DH. DH hates secrets and he loves grandkids, so you do the math on how hurt he is.
