Maybe she isn’t a good lay? Seems they never think of that. Beautiful woman with a big vajaja and no blow job skills is ok to take to parties, but nothing long term unless you get a side chick. Jeez.
There’s no going back. Threesome going on for 4 years. She’s gone. Seek full custody of the kids. No DNA test. These kids are yours, and you are their father. Why second guess it? Public shame is ok… but not permanent online posting stuff the kids will find years from now.
20 years from now “Mom, you said dad was a missing during undercover operations in a foreign country but this website says you were a cheater. Mom, where is dad really?”
Kids could not be mentioned at this age. Not having had raised a kid by 50 would raise more questions. Saying you got kids means you got YOUNG kids (dependents) still in the house.
