What To Do?

As most of you already know if you follow me, I am a proud father of two daughters who I had in a previous marriage and went through an awful divorce. Not only in regards to me, but also for my daughters. I have joint primary custody and want more than anything to get full custody. What pains me the most is having to defend my ex-wife's behavior to my daughters when they don't want to go to see her but are torn as they wish to see their two younger siblings she has since conceived.

This weekend was not a normal visitation weekend but I was selfish because my wife had purchased an awesome birthday present for me and the ex-wife was out of town for her visitation. She has been somewhat civil and asked to have the kids this weekend since she had returned. Against my wife's better judgement I agreed and she drove to us to pick them up.

My wife and I have a great weekend and Sunday morning around 10am I get a call form my ex-wife screaming "Come pick up your thieving as children, stealing money outta my purse and lying!" I and still hocked from the initial screaming and accusations. While I am trying to sort out what is going on, she of course accuses me of being in their area and to turn around and come get them. We live two hours away and she was going to have to wait for me to get there. I hated the fact that we were so far away because I knew the girls were getting worse then I was over the phone.

We leave and in the process I call her back to talk to my oldest daughter and find out what is going on. She is telling me her side of the story about how they found the money at vending machine in the lobby and she assures me she wasn't in her mother's purse nor did she steal anything. Suddenly I hear the ex-wife yell in the background "Tell your daddy to hurry up and come get you. I don't f**king wan't you down here no more no damn way." At this point I am almost livid and my daughter is emotionally upset and beginning to cry. I tell her to go to her grandmother's vehicle who happened to be with them at the time.

The drive gets slightly faster and my blood is racing. I know I have to calm down because our exchange takes place at a police station in a county about 2/3 the distance from my home. When I arrive my daughter is upset and my other daughter is not aware of what is going on other than she was accused of stealing as well. However all the sudden the ex is calm and refusing to say anything. her grandmother is pleasant and asking me to ignore my ex. she doesn't want to lose the visitations as she usually cares for them when they go down there. She assures me nothing happened and everything is okay. She evens gives them enough change to get something from the gas station to snack on for the drive home. I can't believe and I am extremely upset but I try to be calm.

We get my daughters gathered and into the car and drive away and I try to discuss it with my daughters but at this point I no longer have an ounce of desire to defend my ex. i will refrain from speaking badly about er but won't defend her and since my daughter's don't want to see her i won't. The downside is we have a divorce decree that grants her visitation on the 1st and 3rd weekends of each month. So what do I do now...
