Why do I feel this way

I am very depressed today. Chris does not want to have anything to do with me because I told Kelley the truth about us. I told her about the pictures we shared w/ eachother and she went into Chirs' phone and the pictures. This was last week and he still does not want to talk to me as much as he did.
I told him that I miss him, but he said that he knows what he wants, He wants to be single. He still talks to Kelley and she is still demanding him not to talk or see me at all. I still think that they will get back together because he is not talking to me.
He told me that he txted her tonight and she did not respond so he said goodbye to her.. like I said, I know he will get back to her even though she went into his place and snooped around, she went into his phone and saw how much he and I txted eachother and what blows my mind is that she gave another guy a bj in the china's bathroom and he does not care... he said to me "this may sound crazy, but my GIRLFRIEND is mad at me for having sex with my WIFE"........I said to him,, did you just realize what you just said, and he said yes, my GIRLFRIEND> I can't believe he just said that...but he is not happy the fact that she is demanding him to do and not do some things and he is mad at me because I lied to him about meeting someone else and having sex w/ him. It is pretty sad that the only one I have been with is my HUSBAND and he is mad at me because I actually did not have sex with other people..
This does not make any since to me at all.. I just want to hold him and tell him how much I love him........... I should be the one who is mad at him for doing all this shit to me, but I am not. I STILL LOVE HIM. Why??????? Why do I feel this way. Why can't I forget him and let him go on with his life? There are soo many things I don't understand in my life. I hope I can understand one day.
