Trying to cope with H, IA/EA (was Newbie-1st post)

[Faith2010]

The funeral for BIL was really nice. His second oldest daughter gave the Eulogy, which was beautiful. His children are so strong.

Found out H is now texting OW (previously phone calls and Internet). Saw a few of them this morning. There are 'miss you' and 'can't wait to talk to you' and 'love the pics'. OW wrote "love to you and your family." Enough was enough this morning and I tried to call her. Her voice mail picked up. H was furious and said I just lost any chance of working it out. I plan on trying to call her again as I think she needs to know she is destroying a family and the effect her relationship with H is having on our child. Am I completely off the wall here? I know DR does not recommend contacting the OW but it feels like it's spiraling out of control.

Found out from SIL my S told her he has no respect for his father. H did not refrain from speaking on the phone numerous times each day in front of S and others. I have not approached H about the calls due to the circumstances.
