Feeling frustrated,
Almost 20 years with DH,(SD32 and SS38).SS,wife,and Sgk's are great. SD has disrespected our marriage from day one,stealing,splitting parents turning against each other,typical stuff. BM married to lover from adultery which caused DH to divorce her.

SD tries to set up "gatherings" on days when I'm at work,taking pics with the BM and my DH,pretending her parents are "still together".
