Just when I thought it couldn't get any worse

Eric just announced that he is looking for a new place to live. I asked where and he said in Pleasant Grove- Utah County. I have been trying to get him to move to Utah County for years to make his commute shorter and he swore up and down he would never live in Utah County. I asked if it was because of Corilynn and he agreed. I asked if they were moving in together and he said maybe--which is code for YES. So they are looking for a house to live in together. I am not surprised, but of course I am not happy about it at all. I asked him just a couple days ago if they were going to get married, he assured me they weren't. I guess I should have been more to the point...are they getting serious enough to live together and pretend to be married and have their kids pretend to be family. I'm sure he would have said no anyway. I told him if this happened, he would not have the kids during the week. Only on the weekends. Even if it's just him in the house. He thinks he will drive back and forth from Utah County to my house four times a day??? What a stupid thing to do. I told him to think about this. He is definitely not putting the kids needs first. They would have to get up earlier and spend more time driving than they already do. I don't like it now and they only live 15 minutes away. Then he started acting like I was being insane or something. He said sarcastically "Yeah--I'm not putting my kids needs first"... I reminded him of how Montana calls me every night when she is with him and begs for me to come and pick her up. She texts me all night long saying she hates it there and she is not comfortable being the only girl. I asked him how he thinks throwing in a step family is going to be beneficial for her. He just rolled his eyes. I told him the kids are not ready for this. He has only been divorced for 25 days. Hello. I told him he is thinking with his penis and not his head. This was not a good idea. So he just shut me down, got in the car and drove off. How adult of him. I am so furious. I'm humiliated, I feel scared for my kids, and I know now that I am going to have to gear up for an even bigger battle. I hate him.
