The OW started with the kids again, Ex screamed at kids... Now what?

What do you do when you have friends that live in your old neighborhood where your ex lives? How about when the OW lhe left you for lives directly across the street from your firneds? How about when you don't care about what is going on at your ex's or the OW house, you are there to hang with your friends, and your children and their children have been froends since they were toddlers? What if your children went to say hi to thier dad because they love him, and you have no problem with them going there even though they are with you at someone elses house? What is the ex tell the kids that you are at that friends house just to bust his beans and you are a C word? What if he and his woman are yelling profanity out the door about things that happened when you were not even there?%0d%0a%0d%0aMy ex told his children tonight it was him or me, and they said why, you choose "her" the OW over us! You never spend time with us, you never go to our functions, and you never have. You tell, drink, and always change your plans with us. You even blow us off on the holidays, take your GF's kids to football, fishing, camping, and NASCAR, but never invite us or have attempted to include us! So what is to choose? We wanted to say hi, and we get this?%0d%0a%0d%0aWhat would you do? What would you do if your family and friends are stopped in stores and berated about what an aweful person you are, and you kids are told by their friends children that you are a whore, even though you are only in the second long term relationship in your entire life, and the first was their father? I was 16 when I met my ex, and was with him for 16 years, married 12, then what??? He left you for another women and one who lived in your back yard. Tells your youngest daughter she is a B**** from the age of 6 to present, and you beleive it is because she is your twin? Where will the law let me draw the line and allow me to protect the mental health of my children? He lost them for seven months and had to go to parenting classes after attempting to kidnap the kids. My youngest had a vervous break down and is on meds now from the kidnap attempt. I was ordered to force my children to go to their visitations, but now the kids want nothing to do with him. His neighbors daughter is our daughters best friend. Always has been, so now what?
