I agree with you Jo. I wouldn't be mean to him, just barely polite. He told you about 2nd OW to get under your skin. Don't react to it....ever!!! Stay calm, polite, but brief with him. He needs to learn that it's not "all about him". Also, he needs to understand that if he wants to see DD4, he's going to have to give in to you regarding your visits with the other girls. It's time for you to take a very firm stand with him and do not relent JO I agree with Qoe100
I don't understand your comment 'not giving a short reply to Andy one of your childrens dad' - he is the father of ALL four of my girls, not just the little one. Jo, if you don't treat him civil or barely polite, he will take revenge and make your life more difficult. I am suggesting you don't give him any reasons/amunition to get back at you. I want you to have the girs as often as you can have them. If you are always angry with Andy and treat him as such, he will always be doing things to get back at you.
I know Andy is all the girls dad. You have one living with you and the others you don't see much. Maybe that is waht I was refering to?
Also, why do you think I should talk to him? Don't talk to him to be nice to him, but so this hostility between you two does not continue on such a high level. All I am suggesting is to be civil (not chummy or friendly) so he does not think of ways to keep your girls away from you.
I don't deserve to be treated like that so I really don't see why I should grace him with a reply. No you don't deserve to br treated that way. Not talking to him (do always keep the interactions businesslike and short) will just him looking for ways to make you angry and he will most like use the girls as a weapon against you.
If your W had slept with another man behind your back whilst telling you she loved you, wouldn't you kick her out of your house? Yes I would, but I would not do it at the expence of not seeing my kids.
