I feel so damn hurt!

What started how I have felt today is really silly. It's all over an unanswered text message.
I was having such a hard time with the kids last night...I was overwhelmed, angry and tired, and I was unfortuntely not a very nice person to be around. I spoke oh so briefly with with F, and after telling him how bad of a mood I was in, he simply told me to put the kids to bed and lay down. For whatever reason, that was the first thing to bother me. Then I left him a long text message explaining how I couldn't put up with his mixed signals anymore, so I told him to stop contacting me. He didn't reply to that, which just added to the pissed off-ness. I told myself that he probably just didn't get the message, but when I spoke to him this morning, he told me he had read it, I got offended, and he sent me a couple text messages about how sorry he was. Other then that, he completely ignored me. He sent me a few pictures he took of me and the kids, called a few times, then sent me an email asking is I was ignorning him now. That led on to my going overboard with the email thing. To make things short, I again asked him to leave me alone; that he didn't know what the hell he wanted, and I was sick of my feelings being tossed around. All of this is because Labor Day I spent with him and our kids, and by how he treated me, you could've swore we were together. He says it's because of how we've been getting along that he now wants to spend more time with me. Unfortunately for him, the world doesn't work around him or his time table.

He finally called, and he told me he didn't know what to do about us. That he had to stay "true" to the fact that his feelings had changed toward the relationship, but he also had to respect what I asked of him. I feel like quite the fool; this whole time he has been dating this girl, while being married to me, and I stuck around and stuck around, with everyone looking at me like some kind of idiot. I told him that. I told him I was done looking stupid. I told him I was done with my feelings being played with, and that I wanted him to leave me alone.

He did sound sad about it; told me he would leave me alone unless it's an emergency, and he would only talk to me if I initiated a conversation. His reason for this was because he didn't want to hurt my feelings anymore; that he didn't want to cause me anymore confusion and that he wanted my happiness. Why doesn't he understand that I'd be happy with him? Why doesn't he want to fight, or tell me he would leave his GF to make things work because it's important to him? I'm delusional. I'm angry. I'm hurt. In almost 8 years of knowing him, there has been less then a handful of days that I went without talking to him...tomorrow will be hard day, and so will the day after that and the day after that. I am sticking to my guns. I have made the promise to myself that I will not cave, and that I will restrict every and all communication. He wanted the girlfriend and he wanted the divorce...he can no longer say that I never gave him anything.
